The objective of this paper is to introduce digital and analog modulation techniques. Modulation is process of varying some parameter of periodic waveform in order to use that signal to convey a message. If the variation of signal in the parameter of carrier is continuous in accordance to input analog signal, it’s called analog modulation and if variation is discrete it’s called digital modulation.
