Periodic analog signals and Non-periodic digital:
Periodic analog signals are continuous signals that repeat themselves in a regular pattern over time. Examples of periodic analog signals include sine waves, square waves, and triangular waves. These signals have a wide range of amplitudes and frequencies and are commonly used in analog communication systems to transmit continuous signals such as audio, video, and radio signals.
Non-periodic digital signals, on the other hand, represent information using discrete values or symbols. They are binary signals that use only two values, 0 and 1, to represent information. Non-periodic digital signals can be represented by square waves or pulses of varying amplitude, and their duration represents the value of the data being transmitted. Digital signals are used in digital communication systems to transmit digital data such as text, images, and computer programs.
