I'll describe how it works in hardware and then how I've done it in software. Hardware: You have a bank of n capacitors that are hooked to a amplifier via a mux. You use a counter that you start with some sort of trigger that sequentialy connects each cap in turn to the amplifier. The charge and as a consequence the voltage varies depending upon whether the new voltage is higher or lower than the last sample. The assumption being that the signal itself is time invariant and that the variations in signal strength are noise and random in nature. After only 3-4 cycles through the cap bank you begin to pull a workable signal out of the noise. The nice thing is that this works for signals that are below the noise floor and buried in the grass. In a VanEck monitoring situation you'd need a bank of n capacitors where n is the number of horizontal pixels. You will also need to array each bank into a m row matrix where m is the number of scan lines. You can get around some of the bulk by using a gyrator circuit to synthesize the capacitor and some sample-and-holds to synthesize the array. The advantage here over software is that this signal can be sampled as its built in real-time (use instrumentation amps) unless you happen to have dual-port ram in your computer (I've never had access to such hardware) and fed to whatever equipment you want to process it. Software: You take a A/D converter and drive an array with it. You sync it the same sort of way as the hardware methods above. Each element in the array contains the current estimate for that particular sample of the total waveform. Each time you come back to the same array element you compare the last value to the new value. You take the value that is half-way between the two and store that as the new array value for the next cycle. In short order a signal comes out. Either the hardware or software method will naturaly integrate the signal within the sample window because of the capacitor effect. This compensates for clock and signal jitter quite nicely. This method will require a D/A conversion process if you want to feed it to any external equipment. Though it should be perfect for Van Eck monitoring. Simply use your video frame buffer as your sample storage array. Enjoy. ____________________________________________________________________ | | | The obvious is sometimes false; | | The unexpected sometimes true. | | | | Anonymous | | | | | | _____ The Armadillo Group | | ,::////;::-.

Caldera claims that the unnecessary technical tie of MS-DOS into Windows 95 artificially created an impression that DOS on the desktop was dead. In court, Caldera will show that this act and other practices illegally eliminated competition to MS-DOS. This latest court decision allows Caldera to extend its claims of illegal behavior and its request for financial damages to include both historical and existing practices. With this amendment, the courts are allowing Caldera to include consideration of Microsoft's Windows 95, Windows 3.1 and MS-DOS market shares when calculating both the industry effect of Microsoft's alleged monopolistic practices and the financial damages being sought by Caldera. "This amendment to our antitrust case is not about the benefits or features of Windows -- it is about an illegal tie of MS-DOS into Windows 95. We allege Microsoft created this illegal, artificial tie for the dominant purpose of eliminating competition," said Bryan Sparks, President and CEO of Caldera. "The evidence we have to support this new claim coupled with the evidence we have to support our other claims extends our conviction that we will win." Caldera can demonstrate that Windows 95 runs on DR-DOS, Caldera's version of DOS, demonstrating that no technological dependency exists between MS-DOS and Windows 95. In court, Caldera will use this fact to prove that the unnecessary tie between MS-DOS and Windows 95 is one of the many illegal and predatory tactics Microsoft has used and continues to use to maintain its desktop monopoly power. In November 1997, the court denied Microsoft's motion to change the venue of Caldera's trial from Salt Lake City, Utah, to Seattle, Washington. This case is currently scheduled for jury trial in November 1998 in Federal Court located in Salt Lake City, Utah. --------------9A07051BBF5BBA9469DB7E8D-- --- To unsubscribe send the message "unsubscribe alg-l" without quotes to majordomo(a)lists.io.com Send questions to owner-alg-l(a)lists.io.com

He knows as well as anyone that libertarians are not pro-business; they're pro-individual rights. Libertarians spend quite a bit of time complaining about the Republican habit of funding corporate subsidies. The pursuit of profit in the free market is not to be discouraged -- without it, we wouldn't have the Internet we have today. Rather, we should be suspicious of the intersection between the government and the market in Congress and in federal agencies. I've written elsewhere about the dangers of industry sellouts on civil liberties -- sellouts and compromises which are of course opposed by libertarians. The libertarian Cato Institute opposes the McCain bill at issue in this hearing. -Declan

Fourier & Signal Analysis...
by Jim Choate 17 Dec '03

17 Dec '03

Hi, There is one final point I would like to make regarding at least one comment on Fourier Analysis of signals in a noisy environment. Fourier signal analysis is not good for this sort of stuff, what you want is a function called a Laplace Transform. Fourier is a method to take a complex signal and break it down into component trigonometric functions (eg sin) such that we can apply filtering and other frequency dependant operations to the signal to improve the signals characteristic signature or operate on a particular component (ie a component that is resonating with something and decreasing the s/n ratio - ringing on a pulse edge for example). If you want to find a signal in the noise you want to apply a Laplace. What it does is convert the amplitude-time variant signal (ie f(t)) into a power-frequency variant signal (ie f(s)). What this does is take, for example, a sample of a signal and describe how that signals power is divided between the various frequencies in that signal (eg McLauren Series). In most applications the grass of the signal will be evenly distributed across the s-mapping while the signal (at least its carrier component) itself will show up as a spike of noticeable amplitude. The reason you do this in signal analysis is because that transormation function will often be a simpler equation to solve numericaly that actualy trying to deal with f(t). So, if you want to find a signal in a complex environment use a Laplace Transform, once you've found the signal and want to know about its components use a Fourier Transform.

Right now Hong Kong is being run by some rich capitalist chinese.

Blind signatures dead in the water. What now?

Why are blind signatures dead in the water? One obvious reason is that people attempting to do business with David Chaum seem to get rather irritable. Still, despite that, Digicash actually exists, but no one uses it. One reason is that the network to convert Digicash into other forms of value is rather limited, whereas the credit card network is fast and spans the world. Another is that people do not wish to hold large amounts of Digicash] for long periods, (security, no interest) and converting money back and forth between interest bearing forms and Digicash attracts rather high charges. (Or used to attract rather high charges when last I looked.) So where do we go from here? One obvious solution is nymous money-- money that is not anonymous, but is not required to be connected to one's government approved and registered name either. This is arguably better than the half-anonymous money that has in fact been implemented by Digicash. What nymous money projects are happening, and how are they going? --digsig James A.

---------------- Begin Forwarded Message ---------------- Date: 02/09 10:25 PM Received: 02/09 10:29 PM From: James A Chappelow, chappja(a)mail.auburn.edu Reply-To: Vermont Libertarian, vtlp-list(a)catamount.com To: Multiple recipients of, vtlp-list(a)catamount.com Outside of Birmingham, a kid was arrested Saturday for not giving a cop his Social Security number. The bumper fell off his truck, so he stuck the tag in the rear window; not a rare sight in Alabama. He got pulled over for it. Alabama licenses have the holder's SSN on them (because that way the state gets more Federal highway $), except his parents had never applied to get him one, because of their religion. When the cop demanded his SSN ("Deine Papieren!"), and he didn't tell him one, he was arrested for disorderly conduct. He's still in jail because in order to bail him out his parents had to supply their (guess what) SSNs. Clinton recently declared his intention to use his supposed budget surplus to save Social Security. In order to maintain Social Security payments, it is estimated that combined Federal taxes will have to rise to 84% of national income! Social Security is doomed as a retiremant option; there is no reason for any able bodied citizen born after 1950 to ever expect to see any benefits from it. So why should any of those people have SSNs? Because securing retirement is not the real goal of Social Security. However, it is still quite valuable as a means for tracking and controlling people, and it looks like voluntary compliance is now being strictly enforced. That's why Clinton wants to save Social Security. James A. Chappelow --------------------------------------------------- This message is from the VTLP-list (Vermont Libertarian) mailing list.
