Answer the Following and provide solution. 1. The maximum frequency deviation of the carrier is ± 15 kHz and the maximum modulating frequency is 3 kHz, calculate for the modulation index. 2. Assume that the 60-dB bandwidth of a receiver is 12 kHz and the 6-dB bandwidth is 7 kHz. What is the shape factor of the circuit? 3. What is the bandwidth of a receiver with a quality factor of 50 and a resonance frequency of 540 kHz. 4. What is the maximum bandwidth of an FM signal with a deviation of 27 kHz and a maximum modulating signal of 4 kHz as determined by Carson’s rule? 5. A PM signal has a maximum allowed deviation of 17 kHz and an actual deviation of 8 kHz. What is the percentage modulation?
