Digital Signal Processing and Filtering: GSM Codec

Overview The conversion of analogue speech waveform into digital form is usually called speech coding. A major benefit of using speech coding is the possibility to compress the signal, that is, to reduce the bit rate of the digital speech. The efficient digital representation of the speech signal makes it possible to achieve bandwidth efficiency both in the transmission of the signal, e.g. between two antennas in a GSM system, as well as in storing the signal, e.g. on a magnetic media such as a GSM telephone memory.
