PULSE ANALOG MODULATION

PULSE ANALOG MODULATION. A Continuous Time (CT) signal can not be processed by the digital processors. Hence to enable digital transmission of CT, it has to be converted into Discrete Time (DT) signal. ##1 Sampling Therom gives the criteria for spacing Ts between two consecutive samples.
