You are given the task of construct a reciever which combines both analog phase modulation (PM) and analog frequency modulation (FM) recievers. The combined receiver operates only in one of the modes (either analog PM of FM) at a time based on the arbitrary choice of transmitter side user and transmitter side user could change the mode anytime he/she wants during the operation . In other words, your receiver should be designed in such a way that it would decide the instantaneous received signal is either analog PM or FM. Describe the neccesary and sufficient requirements to construct such a receiver. Devise a methodology for the design.
