Question

Whose operations are more faster among the following?

(a) Combinational circuits

(b) Sequential circuits

(c) Latches

(d) Flip-flops

This question was posed to me in a national level competition.

Origin of the question is Flip Flops in chapter Flip-Flops of Digital Circuits

Answer 1

Right answer is (a) Combinational circuits

To elaborate: Combinational circuits are often faster than sequential circuits. Since the combinational circuits do not require memory elements whereas the sequential circuits need memory devices to perform their operations in sequence. Latches and Flip-flops come under sequential circuits.
