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 its way through the flip-flops.
What is the maximum count of ripple counter?
Ripple counter is an Asynchronous counter. It got its name because the clock pulse ripples through the circuit. An n-MOD ripple counter contains n number of flip-flops and the circuit can count up to 2n values before it resets itself to the initial value.
How many counting sequences can a 3-bit binary ripple counter full counting have?
How many pulses a 4-bit ripple counter can count?
4 bit asynchronous ripple counter The counter consists of four flipflops and it can count 16 states. The clock pulse is given to the first flipflop and the normal output of the first flipflop is considered as the clock input of second flipflop and so on.
What is the output of 4-bit ripple counter?
In a 4-bit ripple counter, the output Q0 must be connected externally to input CP1. The input count pulses are applied to clock input CP0. Simultaneous frequency divisions of 2, 4, 8, and 16 are performed at the Q0, Q1, Q2, and Q3 outputs as shown in the function table.
How does a ripple counter work?
It is an asynchronous counter. Different flip-flops are used with a different clock pulse. All the flip-flops are used in toggle mode. Only one flip-flop is applied with an external clock pulse and another flip-flop clock is obtained from the output of the previous flip-flop.
