Thanks for the suggestions. I figured out why my circuit wasn't following the predicted behavior - the power supply I was using was dumping strong 60hz noise into the circuit, which was causing the comparator whose output was feeding the multivibrator to oscillate constantly instead of clamping...
I'm working on a project that uses 3 amps of an LM224N as amplifiers and a comparator; I'd like to use the fourth to trigger an LED for a second or so when the output of the comparator goes low for a visual indicator. I've been trying to set it up as a monostable multivibrator, but I can't find...
@zorro: I don't suppose you'd have any links to examples of actual applications of n-path filters, would you? I searched and searched for n-path filters, and pretty much all I found were white papers with high level theory on places like ieeexplore.ieee.org or google patents...
I'm trying to find the best (simplest/cheapest) solution to detect a specific audio frequency embedded within an audio file. Basically, I'm looking to make an Audiostrobe decoder, but one that I can control the outputs of for various experiments. Audiostrobe embeds a signal at 19200Hz into an...
