Category: Modulation Problem

Solution: What is the amplitude of the carrier?

Solution: What is the modulation index of an FM signal having a carrier swing of 100 kHz

Solution: What is the bandwidth of a narrowband FM signal

Solution: What is the bandwidth (kHz) of an FM signal with 5 kHz maximum frequency deviation

Solution: How much power at 85% modulation with an amplitude modulated transmitter

Solution: Determine its deviation ratio

Solution: Determine the percent modulation of an FM signal which is being broadcast

Solution: What is the maximum phase deviation that can be present in an FM radio

Solution: An FM transmitter outputs 1 kW of power when modulated by a 3 kHz sinusoid

Solution: For a modulation coefficient m = 0.2 and an unmodulated carrier power Pc = 1000 W
