- If you're not concerned about duty cycle, I'd recommend an edge detector
- instead. It's an X-OR gate, with the clock fed into one input, and a
- delayed version of the clock into the other. The output is a pulse train,
- with a pulse occurring for each clock edge that is as wide as the delay
- used on the input.
-
- Example:
-
- +------+ +------+ +-----
- IN ------+ +------+ +------+
-
- +-+ +-+ +-+ +-+ +-+
- OUT ------+ +----+ +----+ +----+ +----+ +---
-
- The interval between output pulses is a function of the input duty cycle;
- interpulse intervals will be equal only for a 50% DC input.
