#1

Write the truth table for the circuits given in figure consisting of N(5R gates identify the logic operations (OR, AND, NOT) performed by the two circuits.


#2

(a) Split the gate,

B is the output of OR gate and input of NOT gate.
So, the gate resembles to NOT gate as A is input and Y is output.

(b) Split the gate,

C is the output of OR gate 1 and input of NOT gate 1
D is the output of OR gate 2 and input of NOT gate 2
E is the output of NOT gate 1; F is the output of NOT gate 2
G is the output of OR gate 3 and input of the NOT gate 3
The truth table resembles to AND gate as A and B inputs and Y is output.

This operation is AND gate.
