communication

Signal Processing is concerned with manipulating of a signal's form. Manipulating of a signal's form occurs in telecommunications, computer engineering, biomedical engineering as well as multimedia systems. A mobile phone is one such example. Before the voice is transmitted, it is changed into waveform suitable for transmission. At the receiver's end it is changed back into the original voice signal.
