PULSE MODULATION TECHNIQUES INTRODUCTION • Modulation is the process of frequency translation in which any one parameter(Amplitude‚ frequency or phase) of high frequency carrier signal is varied in accordance with instantaneous value of low frequency modulating signal. • Modulation is either analog or digital. INTRODUCTION • Many signals in modern communication systems are digital • Additionally‚ analog signals are transmitted digitally • Digitizing a signal results in reduced distortion
