The output y[n] of a frequency-selective LTI discrete-time system with a frequency response exhibits some delay relative to the input x[n] caused by the nonzero phase response of the system

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]}

Sound knowledge of linear algebra and calculus Signals and systems (ECE 351 and ECE 352 or equivalent courses) Basic Matlab programming skillsRequirements
