True or False: For the differential op-amp circuit, your common mode rejection ratio should ideally be 0.

A diode’s resistance in forward bias is measured using a digital multi-meter. Which answer approximately shows a correct resistance value showed by the multi-meter?

If you add two sine wave inputs of the same frequency, the FFT plot of their sum will show 2 peaks.

Assume Vin = 2V, Vdiode_on = 0.7V, R = 1kΩ.  With RL = 10kΩ, what is the current that flows into output load RL? Provide your answer in mA.

In the following frequency response plot blow, find the cutoff frequency.

For the circuit as shown below, Vin= 20 V, R1=15 Ω, R2=R3=10 Ω. What is the value of Vout in volts?

A Zener diode is specially designed to operate in the ________________ region

For the given oscilloscope screen, calculate the period of the signal (in second). Note: volt/div = 2 Volts/div            time/div = 1 ms/div

Which of the following statements are correct: A. The electrical power that we get from the wall outlets is 120V AC(volts, alternating current).  B. The bridge rectifier is the first step in AC to DC conversion. C. A bridge rectifier is an arrangement of four diodes to convert a bipolar AC waveform into a unipolar waveform. D. One way to help regulate the output (AC to DC conversion) is to add a filter capacitor to the output. The larger the capacitor, the more energy it can store, further reducing the ripple effect.

In the bridge rectifier bellow at first we increase C1’s value then we increase R1 value. Choose the correct answer.
