An FM signal has a frequency deviation of 8 kHz and a modulating frequency of 1.2 kHz. The signal-to-noise ratio at the input to the receiver detector is 19.4 dB. Calculate the approximate signal-to-noise ratio (in dB) at the detector output.A sine wave of frequency 7 kHz phase modulates a carrier at 22 MHz. The peak phase deviation is 1 rad. Calculate the maximum frequency deviation in Hz.A phase modulation system operates with a modulation index of 2. What is the maximum phase shift in degrees?
