What is a shift register?
- A.A clocked array of circuits that passes data in steps along the array (correct answer)
- B.An array of operational amplifiers used for tri-state arithmetic operations
- C.A digital mixer
- D.An analog mixer
WhyA shift register is a clocked array of circuits that passes data in steps along the array. A shift register is a chain of clocked storage elements (flip-flops) where each clock pulse moves the stored data one position further along the chain, answer A. It isn't built from operational amplifiers doing arithmetic, and it isn't a digital or analog mixer, those are different circuit functions entirely.
