Description:
- An input to a sequential circuit that changes output and state values at a predetermined rate
Triggering edge:
- Transition of the clock that captures input data
- positive edge-triggered: from low to high
Clock Period (cycle time):
- Time between successive transitions in the same direction (e.g., L→ H)
- e.g., 1ms, 2ns, 500ps
Clock Frequency:
- 1/period
- e.g., 1kHz, 500MHz, 2GHz
