EE4209/EE5809 Digital Audio Technology
The name bandpass communication arises from the fact that in this method
of data communication, the carrier signal lies in the center of frequency band, called a channelthat is allocated to them.
Digital data can be transmitted by means of a baseband signal or a bandpass (ie, modulated) signal.
The baseband signal uses discrete pulses representing 0s and 1s.
The modulated signal uses a carrier frequency and an encoding of data based on periodically altering the frequency,
amplitude, or phases of the signal.
