LPF with OPAMP

01:28:28

2 low pass filter (time const is 0.1ms: 10kHz). One is built with OPAMP (voltage gain is 2), and the other one is built without OPAMP.

I like your nice clear set of op amp presentations.....Is there any special reason for putting a ± pulse supply instead of an ac supply on this one?...the oscilloscope shows the difference.

I want to see the change of wave shape for the rectanble wave which includes all frequency. This is the only reason :)
