Example - Determine the DTFT of Let We can therefore write From Table 3.1, the DTFT of x[n] is given by

Transform-Domain Representation of Discrete-Time Signals Three useful representations of discrete-time sequences in the transform domain: Discrete-time Fourier Transform (DTFT) Discrete Fourier Transform (DFT) z-Transform

BIBO Stability Condition - A discrete-time LTI system is BIBO stable if the output sequence {y[n]} remains bounded for any bounded input sequence{x[n]}
