一、混凝土结构的基本概念 以混凝土为主要材料制作的结构称 为混凝土结构素混凝土结构钢筋混凝土结构型钢混凝土结构钢管混凝土结构预应力混凝土结构

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]}
