a) You have 1 phase comparator and 1 VCO. Use these two components to draw the block diagram of a 1st order PLL. Assume that s(t) is the FM signal that is input to the PLL and v(t) is the output of the PLL b) Assume s(t) is an FM signal modulated with k 5kHz/V. Assume the VCO uses the same carrier signal as in the FM signal and uses ky 1kHz/V. Assume with the FM signal was modulated with the message signal m(t)-3 cos(2T 200t). What is the output v(t) of the system? c) Assume that the FM signal was modulated with a lowpass signal m(t) with bandwidth 4kHz. Which value of ky would be most suitable to have the least distortion in v(t)? 2kHz/V 3kHz/V 4kHz/V 5kHz/V
