A multiplexed display circuit uses a technique called time division modulation.

In an asynchronous counter, each state is clocked by the same pulse.

Counters are common components in digital clocks.

A serial-in, serial-out shift register transfers data from one line of a parallel bus to another line one bit at a time.

The serial-in, parallel-out shift register transfers data from one parallel data bus to another parallel data bus one bit at a time across a single line.
