An n stage ripple counter can count upto ___________.
An n stage ripple counter can count upto 2n-1.
All subsequent flip-flops are clocked by the output of the preceding flip-flop. Asynchronous counters are also called ripple-counters because of the way the clock pulse ripples it way through the flip-flops. The MOD of the ripple counter or asynchronous counter is 2n if n flip-flops are used.
The clock input or the information ripples through the consecutive flip flops in asynchronous counters that is the clock input to a flip flop is the output of the preceeding flip flop. Hence they are also termed as ripple counters.
A n-bit ripple counter can count up to 2n states. It is also known as MOD n counter. It is known as ripple counter because of the way the clock pulse ripples its way through the flip-flops.
A ripple counter is an asynchronous counter where only the first flip-flop is clocked by an external clock. All subsequent flip-flops are clocked by the output of the preceding flip-flop. Asynchronous counters are also called ripple-counters because of the way the clock pulse ripples it way through the flip-flops.
