Question

a. An AM transmitter has the unmodulated carrier power of 20kW and can be modulated to a maximum of 70% before the system saturates/overloads. Find the value to which carrier power can be increased if 40% modulation limit is imposed.

b. An analog communication system using FM has the highest modulating frequency of 5 kHz and maximum deviation of 25 kHz. Calculate the bandwidth of modulated signal using Carson’s rule. Compare this value with the one obtained using the simple formula. For practical systems which of these values should be used?
