Digitization and Discrete Systems,e measurement. Discrete-time signals can be processed by discrete systems which behave similar to analog systems in many ways. The convolution sum is the discrete-time form of the continuous-time convolution integral. This defines the basic input–output relation of discrete-time systems.

Discrete Signal Processing,within a small time window, and only low frequency components need large time windows. An alternative to using Fourier and time-frequency analysis is to use purely time-domain analysis, like time-series methods.

Signal Measurement,ve model of the system. The measurement model postulates characteristics of the signal of interest that distinguish it from interfering noise. The two main purposes of signal analysis and system modeling in physiology are (a) to reduce the contaminating noise in the observed signal and (bi) to descr

Signals and Systems Basics, real biological system is nonlinear and time variant, for simplicity of analysis we assume that physiological systems are linear in the range of interest and time invariant in short intervals subjected to analysis. Convolution is a mathematical technique that defines the input–output relation of a
