[SHAMELESS PLUG] Possibly relevant to "On old electrolytic caps" thread, but also for general interest, I've just released Daqarta v7.60 which includes a macro "mini-app" to use your sound card as an LCR meter. (Many thanks to Robert A. Macy for inspiration and advice on this!) The basic idea is that the sound card outputs a sine wave (about 1 kHz default) that drives a voltage divider m...

Hello all, I'm back again with an audio zero-cross detection circuit that I have desig= ned based on valuable feedback from some of you (notably Jim Thompson and J= ohn Fields). I am trying to gate an audio signal while avoiding clicks as i= t switches on and off. I'm submitting the LTSpice file here for your comments and also to ask why = one thing does not seem to be working as intende...


Simulating Power Bandwidth

I'm trying to do a simulation to show power bandwidth for a (high power) OpAmp versus compensation capacitor. In the lab I would simply crank up the signal generator amplitude until the output became triangular rather than sinusoidal. Collect all the data for peak amplitudes versus frequency and then plot. Any ideas how I might do that automatically in a simulator, generating a family...

Hello again, It is time for me to acquire a better bench top power solution. Most of the time I will use it to power a breadboard for experimentation. I used a wall wart for awhile until it got super noisy, and batteries are a hassle. I was about to go for something like this: http://tinyurl.com/qexphfy And then attach something like this: http://tinyurl.com/qc5e9ma to the leads ...
