Beginner Topic 15 of 51 Computer Architecture & Logic

Clock Signal

Periodic pulse synchronizing sequential logic.

How it works

The clock is a periodic square wave; sequential logic updates on its edges. Clock speed (Hz) is bounded by the longest combinational path between registers.

Where it is used

Synchronizing every part of a processor.

Common pitfall

Clock skew and crossing between clock domains require careful design.

Where it fits in the course

Clock Signal is topic 15 of 51 in Computer Architecture & Logic, rated Beginner. It follows Registers. The next topic is Von Neumann Architecture.
