Choose the correct option

The octal binary system is inefficient for microprocessors

Noise margin is not a characteristic of digital IC

All of the above

Latches are faster than flip-flops

Solution:

which of the following option is incorrect?

full adder is a combinational logic circuit.

full adder adds three binary bits at a time

to implement a full adder, 1 XOR gate, 3 AND gates and 1OR gate is required.

a full adder can be implemented by logically connecting three half adders and OR gate.
