The maximum frequency deviation of the carrier is 15 kHz and the maximum modulating frequency is kHz. Calculate the modulation index. Assume that the 60-dB bandwidth of the receiver is 12 kHz and the 6-dB bandwidth is kHz. What is the shape factor of the circuit? What is the bandwidth of a receiver with a quality factor of 50 and a resonance frequency of 540 kHz? What is the maximum bandwidth of an FM signal with a deviation of 27 kHz and a maximum modulating signal of kHz as determined by Carson's rule? A PM signal has a maximum allowed deviation of 17 kHz and an actual deviation of 8 kHz. What is the percentage modulation?
