Carrier of the Carries Frequency Deviation Power of the Carrier Signal Modulation Rate Frequency {+Peak, -Peak, Average, PeakToPeak, RMS} High Pass Freqyency Low Pass Freqyency Band Pass Freqyency of CCIT This process measures the Deviation Frequency of a Frequency Modulated (FM) signal. The deviation is used to describe the maximum difference between an FM modulated frequency and the nominal carrier frequency
