Signals & System
Lecture 4
Linear Systems and Convolution
Dr. Tahir Zaidi
,Lecture 4: Linear Systems and Convolution
Linear systems, Convolution: Impulse response,
input signals as continuum of impulses. Convolution,
discrete-time and continuous-time. LTI systems and
convolution
Specific objectives for today:
We’re looking at discrete time signals and systems
• Understand a system’s impulse response properties
• Show how any input signal can be decomposed into
a continuum of impulses
• DT Convolution for time varying and time invariant
