Cascadable Counter Definition/Meaning:
An individual counter element, usually a flip-flop,
in a chain of such elements. Each element has facilities for a count input and
is capable of generating an overflow (or carry) output. The counter elements may
typically have count lengths of integer powers of 2 (binary counters) or integer
powers of 10 (decimal counters). Cascading a counter that has a count length of
4 with one having a count length of 10 will give a counter that has a count
length of 40.
Since cascadable counters are available as integrated-circuit blocks or
modules, cascadable counters are also called modular counters.
