MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Asynchronous counters are slower than synchronous counters because of the delay in the transmission of the pulses from flip-flop to flip-flop. Asynchronous counters are also called ripple-counters because of the way the clock pulse ripples it way through the flip-flops.

Detailed explanation-2: -Answer: Ripple Counters are also called Asynchronous counters. In the ripple counter, the flip-flops are arranged in a cascaded manner where the output of one flip-flop drives the clock input of the next flip-flop. The number of flip-flops in a cascade arrangement on the basis of the number of different logic states.

Detailed explanation-3: -Asynchronous Counters. If the flip-flops do not receive the same clock signal, then that counter is called as Asynchronous counter. The output of system clock is applied as clock signal only to first flip-flop.

Detailed explanation-4: -Asynchronous circuit (clockless or self-timed circuit) is a sequential digital logic circuit that does not use a global clock circuit or signal generator to synchronize its components.

Detailed explanation-5: -It is known as ripple counter because of the way the clock pulse ripples its way through the flip-flops. Some of the features of ripple counter are: It is an asynchronous counter. Different flip-flops are used with a different clock pulse.
