hi
I want to draw the impedance of the Twin_T circuit, so I run the above schematic in ltspice. I draw v(v1)/i(v1) to show impedance.
Twin_t impedance must show a figure like a bandpass filter.
namely, what I expect is that impedance rises and in f=1/2pi*r*c=25hz takes a pick and then falls.
but after simulation, only a fall is seen.
what is the problem?
