Interview Questions Based On Digital Electronics

Question1. What is difference between latch and flip-flop?

Answer: The main difference between latch and FF is that latches are level sensitive while FF is edge sensitive. They both require the use of clock signal and are used in sequential logic. For a latch, the output tracks the input when the clock signal is high, so as long as the clock is logic 1, the output can change if the input also changes.

FF on the other hand, will store the input only when there is a rising/falling edge of the clock. Latch is sensitive to glitches on enable pin, whereas flip-flop is immune to glitches. Latches take fewer gates (also less power) to implement than flip-flops. Latches are faster than flip-flops.

Question2. Given only two xor gates one must function as buffer and another as inverter?

Answer: Tie one of xor gates input to 1 it will act as inverter. Tie one of xor gates input to 0 it will act as buffer.

Question3. How to achieve 180 degree exact phase shift?


  1. a) DCM an inbuilt resource in most of FPGA can be configured to get 180 degree phase shift.
  2. b) BUFGDS that is differential signaling buffers which are also inbuilt resource of most of FPGA can be used. Digital Electronics Solved Questions

Question5. What is communication?

Answer: Communication means transferring a signal from the transmitter which passes through a medium then the output is obtained at the receiver. (or)communication says as transferring of message from one place to another place called communication.

Question6. What is sampling?

Answer: The process of obtaining a set of samples from a continuous function of time x(t) is referred to as sampling.

Question7. State sampling theorem.

Answer: It states that, while taking the samples of a continuous signal, it has to be taken care that the sampling rate is equal to or greater than twice the cut off frequency and the minimum sampling rate is known as the Nyquist rate.

Question8. What is cut-off frequency?

Answer: The frequency at which the response is -3dB with respect to the maximum response.

Question9. What is pass band?

Answer: Passband is the range of frequencies or wavelengths that can pass through a filter without being attenuated.

Question10. What is stop band?

Answer: A stopband is a band of frequencies, between specified limits, in which a circuit, such as a filter or telephone circuit, does not let signals through, or the attenuation is above the required stopband attenuation level.
