2. You have a modem that can operate at a symbol rate of 9,600. Design a modulation system to allow the modem to transmit at a data rate of 76,800 bps. Specifically, you need to indicate how many amplitude levels and phase levels this modem must be able to generate. (Your design should vary both the amplitude and the phase of the carrier wave signal.) a) Required total alternative signal states: b) Amplitude levels: c) Phase levels:
