Impedence Try 1

The Fast Track to Your Extra Class Ham Radio Licence

Michael Burnette, AF7KB




An attempt to use sound devices to inject a signal and measure the output of simple RC low and high-pass filters (wrote software for analysis). Apparently impedance is a difficult topic for many would-be HAMs. Once upon a time I learned this, but it's been awhile. I was going to do a video but my measurements are pretty far off. I don't know how to account for it.
