Design a narrow band FM modulator and demodulator units based on the following rules. By using your design, assume that you are planning to broadcast music and listen to it.
Design Principles:
- bandwidth of message signal will be 6kHz in case of double sideband solutions.
- the carrier frequency is 4MHz.
- Allowable maximum frequency deviation the system 50kHz.
a) Determine the values of elements (if any; R, C, and L) used in the circuits.
b) In case of noise 
( added to the modulated signal,
- What can be the SNR at i/p stage of demodulator?
- What can be the SNR at o/p stage of demodulator?
(No = 2x10-8W.Hz (No = 2x10-8W.Hz
