Hey folks,
I have spent the last two hours trying to test an active low pass filter. The idea was similar to the passive LPF design: Test a filter without the FET to ensure proper operation and then add an FET. Well I've used four different oscilloscopes, tested multiple op amps, changed my resistors and capacitors, and I still haven't gotten a simple filter to work. WHAT THE HECK? I've got a major test tomorrow and multiple homework assignments to finish tonight so I'll have to come back to this and try again later. Sorry there is nothing exciting to report. I'll simulate the circuit before I come back in for a practical test, hopefully something will have changed. I've checked my circuit tons of times and everything is as it should be. It's possibly just faulty equipment... who knows...
-Mark
