Answer all question.
Identify two ways in which noise affects an FM signal. (Check all that apply.) Noise introduces amplitude variations in an otherwise constant amplitude signal. Noise introduces frequency variations in an otherwise constant frequency signal. Noise causes amplitude shift and hence phase shift. Noise causes frequency shift and hence phase shift.
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?
