WebMay 16, 2010 · Power is proportional to N, but peak voltage when all signals are in phase, is also proportional with N, so Peak power is proportional with N^2. The probability of getting the PEP value is very low for large N, and this can be used to modify the signal (accept errors or avoiding certain bit patterns, etc).
