Question

Question 1 10 First lets consider the following digital circuit I Q2 2 CIK If 'is equal to what is this componentas noted by the dotted square Select] This component will be tripper and process the inputs when the Cik is select Now lets consider the following component 00 What component is this Select #CO and D-Othen the output of this componenti Select HC-and-then the output of this component is the HC-1 and then the output of this componentis Select WC ad D1 then the output of this componenti Select Now les consider the folk Component . The 1s complement of will at the output when Ais? Seed ch

Answer 1

Greetings!!

1. 8 bit register

2. Rising edge of the clock

3. 4x1 multiplexer

C=0,D=0 then Output=X1

C=0,D=1 then Output=X1'

C=1,D=0 then Output=0

C=1,D=1 then Output=Q1

4. When A=0, 1's complement of X1

5. 1's complement is added with 1 will give 2's complement.

So E=1, and B=0

6. This circuit is an 8 bit Adder/Subtractor which can store the answer into the 8 bit register connected.

[Please note that the above mentioned circuit can do many operations but Addition and Subtraction are the main operations]

2's complement of X:

A=0,B=0,C=0,D=0,E=1

13 in binary 00001101

1's complement 11110010

2's complement 11110011

Answer is 11110011

Hope this helps

Thank You
