Detailed explanation-1: -The continuous variation of the amplitude, width, or position of the pulses in a pulse train to represent an information signal is defined as analog pulse modulation (examples are shown in Figure 1).
Detailed explanation-2: -Digital Signals. Digital and analog signals are transmitted through electromagnetic waves. Changes in frequency and amplitude create the music you listen to or images that you see on a screen. Analog signals are composed of continuous waves that can have any values for frequency and amplitude.
Detailed explanation-3: -The process of efficiently converting the output of either an analog or digital source into a sequence of binary digits is called source encoding or data compression. The sequence of binary digits from the source encoder, which we call the information sequence, is passed to the channel encoder.
