clock signal divider
There are five flip-flops in a five-bit ripple counter.
a mod-10 counter is a basic formula for the male and female combination !
12 mod design
Clock is propagated from one T or JK flip flop to another hence it works. A ripple counter works by the following principle. A clock pulse is applied to the first flip flop and the output of the first flip flop acts as the clock input to the second flip flop and the sequence continues in that order.
binary coded decimal counter with carry propagated bit to bit by ripple method instead of carry lookahead combinatorial logic method. this is easy to build but has long settling time with invalid codes occurring before it settles. for example these counters will generate a 1010 code between 1001 and 0000.
A ripple counter is a counter in which state transitions of one or more flip flops are triggered by the outputs of other flip flops in the circuit. If all flip flops in the counter are triggered by a common clock pulse, then the counter is called a "synchronous counter". a ripple counter is a counter that will ripple through the information sequentialy. .
brief explanation of asynchronous ripple counter
There are five flip-flops in a five-bit ripple counter.
Add a circuit to reset it when it hits 10. Yes it will glitch, but ripple counters already glitch.
A synchronous counter is not referred to as a ripple counter. They are two different things. The ripple counter uses the output of each stage to trigger the input of the next stage, resulting in propagation delay between stages. The synchronous counter, on the other hand clocks all stages on the same clock edge, making them all change at relatively the same time.
The word ripple in ripple counter refers to the fact that the carry ripples from one flipflop to the next, instead of being pre-calculated by logic so that all the flipflops in the counter change state synchronously. Thus the bits in a ripple counter change state asynchronously with the most significant bits changing last. This can produce race conditions and instabilities in logic circuits that are driven by these counters.

its like a 555 timer chip. if you know wht that is
The parallel counter incorporates carry lookahead circuits so that all flip-flops in the counter change in sync with the clock pulse. The ripple counter each flip-flop output is the clock for the next flip-flop, causing the most significant bit of the counter to settle only after a long delay time from the input clock pulse.
