Signals & Signal Processing || DSP || Bangla Lecture

Описание: Anything that carries information can be called as signal.
It can also be defined as a physical quantity that varies with time, position, temperature, pressure or with any independent variables (such as speech signal or video signal).
The process of operation in which the characteristics of a signal: amplitude, shape, phase, frequency, etc. undergoes a change is known as signal processing.
