Based on the following circuit, how many peaks would you see on the FFT result of the Vout? Let FG1 be a 1 kHz, 500 mVpp sine wave, and let FG2  be a 3 kHz, 2 Vpp square wave. For Vin3, let the signal be connect to GND (not +4 volts).

Calculate the pass band gain (K) for

Consider a second order active low-pass filter as shown below. Assume the measured resistance of pot is 5.1k Ohm at 10Hz, what is the calculated quality factor of this filter?

What is the minimum theoretical gain for a non-inverting op-amp amplifier? By minimum, we mean the gain that is closest to zero.

Consider the following ideal op-amp circuit. The minimum-maximum range of Vout depends on the value of RL. Assume that RL > 0.

What is its cutoff frequency of the following high-pass filter? Report your answer in Hz to the nearest 0.1 Hz.

A signal of frequency 60 Hz is the input to a full-wave bridge rectifier. What is the frequency of the output signal (in Hz)?

Select that best applies. Assume JFET has a negative pinch-off voltage . If the input generated from FG2+ increases in magnitude, i.e.

Connecting a load resistor to a passive, first-order highpass filter will decrease the cutoff frequency.

Calculate the resonance frequency in Hz of the passive first order low pass filter as shown below.
