freqeuncy and phase sensitivity

时间:04-05 整理:3721RD 点击:
Hello.
What is the typical value of frequency sensitivity (kf) in FM and phase sensitivity(kp) in PM?

thanks

kf is a constant and is expressed in Hz/V (or rad/V in case of phase modulation, kp). It is very similar with the VCO gain which also is expressed in Hz/V, with the difference that kf is the instantaneous value of the frequency that is linearly modulated by the voice or by the baseband signal. To find its value have to know the frequency deviation (Δf) of the FM signal.
kf = Δf/A ; where Δf is the deviation frequency and A is the amplitude of the modulation signal.
kf have large values for Wide-FM modulations, and low values for Narrow-FM modulations.

kf = 0 to 1 or any integer value, perhaps with experimental value
