Fundamentals of discrete-time signal Discrete-time signals: processing • Signals: physical quantities that change as a function of time, space, or some other dependent variable. Objective of this chapter: • Analysis of signals require mathematical signal To focus attention on some ...
9.6 Correlation of Discrete-Time Signals A signal operation similar to signal convolution, but with completely different physical meaning, is signal correlation. The signal correlation operation can be performed either with one signal (autocorrelation) or between two different signals (crosscorrelation) ...
Discrete-time representation of continuous-time signals 1 Physical signals are usually dened in continuous time, but signal processing is done more eciently digitally and for discrete-time signals. A continuous-time signal x (t) is specied by an c (uncountable) innite number of ...
