Circuit Identification from the behavioural table

Question

Problem: Circuit Identification from the behavioural table. Solve this hands-on electronics task on EWskills.

Accepted Answer

The table in the question indicates behaviour of 4-bit bidirectional shift register

From the behaviour table, observe that the data shifts by one bit position after every positive clock pulse.
The Shift Control (C) input determines the direction of shifting: C = 1 performs a right shift, while C = 0 performs a left shift.
The Data Input (D) provides the new serial bit that enters the register during each shift operation.
This behaviour corresponds to a 4-bit Bidirectional Shift Register.
A bidirectional shift register can shift stored data in both left and right directions, depending on the shift select input.
It stores 4 bits of data and updates its contents synchronously on each positive clock edge.
The serial data input allows new data bits to enter the register while shifting.

Applications: Bidirectional shift registers are used in serial-to-serial data transfer, data buffering, digital communication interfaces, arithmetic shift operations, and data manipulation in microprocessors and embedded systems.
