Ultra low noise amplifier

[moodz]

... the TX / Flyback pulse and the electronics that protects the first amplifier input "chops" any low frequency noises from the coil. This modulates the low frequency components onto the higher frequency components that we want to demodulate to detect targets. The modulation components will appear as sidebands ... very easy to see in a simulation or a real circuit with sensitive FFT spectrum analyser. You cannot easily remove these sideband components with filters as the signals have undergone convolution. Luckily I have a patent that solves this issue and in due time the solution will become clear.

Last time a picture was posted of circuit boards a certain company lost the plot and started spitting out legal threats, i wonder if Ford does this if you lift the hood and photograph the engine?

AS an experiment, use a detector in cancel mode and the direct connect the RX coil directly to one of the input stage bypassing the 2 noise generators, now up the gain. Too much information, pull head in.lol

And that company approached you and asked for the unprotected circuit boards and you got a brand new GPX4500 valued at around $5700 for your trouble, so what are you complaining about Woody??
