Using AM/FM Metrics
Modulation Metrics
FM deviation The FM deviation reflects the amount of the frequency modulation to which
the baseband signal modulates the carrier signal. The quantity being
measured is the peak frequency deviation that is the maximum frequency
excursion from the carrier frequency.
Carrier power This measures the power of the carrier signal without the modulation. Ideally,
power for a sinusoidal carrier signal is concentrated around its carrier
frequency.
