What is meant by Digital Signal Processing?

As the name suggests, Digital Signal Processing is the way of processing digital signals by means of computers, or other highly complex processors with the aim of providing error-free communication. In simple words, it refers to modifying a signal to make it much more efficient and hence lead to better transfer of information. DSP involves applying algorithms and mathematical manipulations to a signal in order to make its quality better than before.

It is important the signals are thoroughly processed so that the crucial information they might contain does not get attenuated while they are being transmitted. A processed signal can be analysed better, displayed well or can be converted to any other type that would be needed with greater ease. Certain converters such as Analog to Digital Converters (ADC) are also used along with digital signal processors. For instance, analogue quantities like, light, temperature, sound, heat, pressure signals are detected and given as input to these ADCs which convert them to a suitable digital form. It is then the DSPs (Digital Signal Processors) that perform computations on these converted digital form and pass on this processed signals to DACs (Digital to Analog Converters) that convert this back into an analogue form (in this case, the light, heat, temperature signals) for real-world use.
