Three-Stage Bandpass Filter

193

Both low and high pass filters to get the "Q" and pass band width we want.  With slightly different resonant frequencies on multiple tuned circuits can adjust width of passband.

Two 1 micro ohm resistors added to run in simulation.

Change frequency source away from 3.742 MHz. and note the drop from 1 volt that the circuit filter effect will cause.

Great illustration. I think it's a bit easier to see what's going on by using the Bode Plot (frequency response) feature. That's the yellow triangle button with the letter "f" in it. (In case you didn't know about it 🙂).

Thanks for mentioning the frequency response feature.
