1. The clock used in digital circuits is the chief contributor of radiated and conducted EMI. IC companies reduced the peak EMI radiated by modulating the clock.
1. How is the EMI related to the clock frequency variation?
2. Which method of modulation is the best method?
1. AM
2. FM (or PM)
3. Are there any undesirable effects in clock characteristics due to modulation?
4. Come to think of it, what are the important characteristics of a clock used in digital circuits?
5. What other clock characteristics can be manipulated to reduce peak EMI ?
