What is the use of cascaded counters?

Answer:

Cascaded counters are used to divide a high-frequency clock signal to obtain a highly accurate pulse frequency.

The cascade is the larger counters that can be built by combining smaller counters together.

What are the counters?

A counter is a sequential circuit with 0 inputs and n outputs. Thus, the value after the clock transition depends only on old values of the outputs.

For a counter, the values of the outputs are interpreted as a sequence of binary digits (see the section on binary arithmetic). We shall call the outputs o0, o1, …, on-1.

The value of the outputs for the counter after a clock transition is a binary number which is one plus the binary number of the outputs before the clock transition.

We can explain this behavior more formally with a state table. As an example, let us take a counter with n = 4. The left side of the state table contains 4 columns, labeled o0, o1, o2, and o3. This means that the state table has 16 rows. Here it is in full

What is cascaded counter?

A counter circuit is usually constructed of a number of flip-flops connected in cascade. Counters are a very widely used component in digital circuits, and are manufactured as separate integrated circuits and also incorporated as parts of larger integrated circuits.
