Question

the group of bits 11001 is serially shifted (right - most bit first) into a 5 - bit parallel output shift register with an initial state 01110. after three clock pulses, the register contains

Explanation:

Step1: Understand serial - shift operation

In serial - shift operation, bits are shifted in one by one starting from the right - most bit of the input sequence.

Step2: First clock pulse

The right - most bit of 11001 is 1. The initial state of the register is 01110. After the first clock pulse, the register state becomes 10111 (the right - most bit of the input replaces the left - most bit of the register).

Step3: Second clock pulse

The next bit of 11001 is 0. After the second clock pulse, the register state becomes 01011.

Step4: Third clock pulse

The next bit of 11001 is 0. After the third clock pulse, the register state becomes 00101.

Answer:

00101
