Pengantar Sinyal & Sistem (3)

SinyalA signal represents a set of one or more variables andis used to convey the characteristic information (orthe attributes) of a physical phenomenon.

Sistem

Signals are always associated with one or moresystems. For example, a certain system may generatethe signal while another may operate on it in order to

process it or to extract relevant information from it.The representation of a system with its associatedinput and output signals.

Time Domain

Signal is represented as a function of time

(as time moves forward, the amplitudechanges).

Frequency Domain

Signal is represented as a summation ofsinusoidal signals (each sinusoidal signalhas its own amplitude and frequency).
