To prevent false alarms produced by a single sensor activation, the alarm will be triggered only when at least two sensors activate simultaneously.

Related Pages A Truncated Ripple Counter uses external logic to repeat a ripple counter at a specific count rather than run through all possible combinations of the bit patterns before repeating itself. After counting these values, the counter resets itself and starts counting again from 00, 01, 10, and 1.
The count values until the clock pulses are passed to J 0 K 0 flip flop. JavaTpoint offers too many high quality services. Mail us on [email protected] , to get more information about given services.

So they are elementary in design and also are less expensive. Ripple counter — A n-bit ripple counter can count up to 2 n 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. Some of the features of ripple counter are: 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. A counter may be an up counter that counts upwards or can be a down counter that counts downwards or can do both i. The sequence of counting usually gets repeated after a limit.
When counting up, for n-bit counter the count sequence goes from , , , … , , , , … etc. When counting down the count sequence goes in the opposite manner: , , … , , , , , … etc. A 3-bit Ripple counter using JK flip-flop —.
