Practice Shift Registers MCQs with four options, answers and explanations for focused Electronics & Telecommunication Engineering revision.

Question 1
Digital ElectronicsShift Registers

A shift register is primarily used to?

  • AAmplify analog voltage
  • BStore and shift binary data
  • CGenerate sinusoidal signals
  • DMeasure resistance
Report an error
Correct Answer: B. Store and shift binary data
Explanation: A shift register is a group of flip-flops used to store binary information and shift it from one stage to another.

Question 4
Digital ElectronicsShift Registers

A 16-bit shift register is clocked at 2 MHz. Ignoring loading overhead, how long does it take to shift 16 serial bits through 16 clock periods?

  • A1 microsecond
  • B4 microseconds
  • C8 microseconds
  • D16 microseconds
Report an error
Correct Answer: C. 8 microseconds
Explanation: At 2 MHz, one clock period is 0.5 microsecond. Sixteen clock periods therefore require 16 × 0.5 = 8 microseconds.
