SO I should ask why we Buffer op-amps are used in electronics?Your second opamp is already giving exactly the same input impedance as the first one, which is why the first one is doing absolutely nothing.
What is a buffer? Is not it a current amplifier with voltage gain of equal to 1.
I meant using 2 coil on one core, one with several wounds and the other with higher woundsNo, that simply alters the tuning.
You won't get any quality, it's AM![]()
