Sinusoidal waveform: Discrete time sinusoidal wave: A discrete time sinusoidal waveform is denoted by, x(n) = A sin (wn) Here a = amplitude and w = angular frequency = 2πf This waveform is as shown in figure below: Similarly a discrete time cosine waveform is expressed as, x(n) = A cos (wn) Continuous time sinusoidal […]
