9) a) An FM signal is described by s(t) = cos(2π × 10ºt + 0.001 sin(2π × 107t)). (i) Approximate the signal bandwidth. (ii) Determine the minimum instantaneous frequency. b) In the context of Binary Phase Shift Keying (BPSK): (i) Discuss briefly why envelope detection cannot work as a non-coherent demodulation scheme. (ii) Assuming the binary data consists of 01100111, show how differential encoding can be employed. Briefly provide all relevant details.
