A first-order passive low pass filter usually has one end of the resistor connected to a function generator, and the other end connected to a capacitor to ground. If another capacitor of the same value as the first capacitor is connected across the first capacitor, how will the cutoff frequency be affected?

Calculate the pass band gain (K) for

Here is the design of an active low-pass filter. The value of R = 31.83kΩ Ignoring the output capacitor, what is the cut-off frequency of this active low-pass filter in Hz?

The schematic circuit of a second order low-pass filter is shown below. If the pass band gain K=2, RB=5.1kΩ, calculate the resistance of RA in

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).

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)?
