## Draw the circuit for an active differentiator with the largest possible frequency response magnitude at 1 Hz.

You have available two resistors of 100 Ω and 1000 Ω, two capacitors of 10 µF and 100 µF and one ideal operational amplifier (with its noninverting input grounded) from which to design some active filters. (a) Draw the circuit for an active lowpass filter with a corner frequency of 159 Hz. Be sure to label the values of the resistor(s) and capacitor(s). (b) Draw the circuit for an active differentiator with the largest possible frequency response magnitude at 1 Hz. Be sure to label the values of the resistor(s) and capacitor(s). (c) Draw the circuit for an active bandpass filter. Make the low corner frequency and the high corner frequency as far apart as possible. Be sure to label the values of the resistor(s) and capacitor(s).
