Lecture 10:The Discrete-Time Sampling (m27545)
Keywords: Digital Signal Processing., DT signals.
Summary: Sampling of DT signals is an important tool for digital signal processing.
Language: English
Popularity: 9.55%
Revised: 2009-07-07
Revisions: New
Lecture 11:Sinusoidal Steady-State (SSS) Or Frequency Response (m27536)
Keywords: Frequency Response., Sinusoidal Steady-State.
Summary: SSS response essentially characterizes the system function. SSS response is commonly used to measure the system function. A common mode of thinking for signal processing tasks is “filtering.” All physical systems act as filters of their input signals. Filtering is an important signal processing method.

Lecture 12:Interconnected Systems And Feedback (m27566)
Keywords: Feedback Systems., Interconnection of Systems.
Summary: Signals normally pass through interconnections of subsystems. Feedback provides an opportunity to use and to integrate material we have learned (Laplace transform, frequency response, step response) in an important application area. Stability is an important issue with feedback systems. Unstable systems can be stabilized with feedback.
