Chapter 4, Problem 68E

Explanation of Solution

a.

Combinational circuit with memory elements:

  • A circuit used in memory is the sequential circuit. Because, the present state output of the circuit as the input of the circuit to determine the next state output.
    • The output of sequential circuit is determined by its present input values and also by its past output of the sequential circuit.
  • One type of the memory circuit is S-R latch...

Explanation of Solution

b.

Number of digits is stored in S-R latch:

  • S-R latch:
    • S-R latch is a type of memory circuit.
    • It is a sequential circuit because the present state output of the circuit as the input of the circuit to determine the next state output.
    • An S-R latch can store the single binary digit values (0 or 1).
    • Block diagram for the S-R latch is shown below:

Explanation of Solution

c.

Output of the S-R latch:

  • S-R latch:
    • S-R latch is a type of memory circuit.
    • It is a sequential circuit because the present state output of the circuit as the input of the circuit to determine the next state output.
    • An S-R latch can store the single binary digit values (0 or 1).
    • The design of the S-R latch circuit produces two outputs, X and Y.
    • The outputs of the S-R latch always complement each other.
      • When the output X is 0, then Y is 1. Likewise, when the output X is 1, then Y is 0.
    • Block diagram for the S-R latch is shown below:

  • From the S-R latch diagram:
    • S and R are the input for the first and second NAND gate, respectively.
    • The output X is another input for the second NAND gate, and the output Y is another input for the first NAND gate...
