A scheme of simple band-pass RC- and LR- filters on operational amplifiers containing only one capacitor or inductor and 3 resistors is proposed. A comparison is made of the amplitude-frequency ...
To sketch the magnitude, we let assume the values 0, 1/RC, and . Then, as for and as To sketch the phase response, we use the result of the phase angle. Then, as as for as . The magnitude and phase ...
