In recent years, there has been an increasing demand for digital transmission and storage systems. This demand has been accelerated by the rapid development and availability of VLSI technology and digital processing. It is frequently the case that a digital system must be fully reliable, as a single error may shutdown the whole system, or cause unacceptable corruption of data, e.g. in a bank account. In situations such as this error control must be employed so that an error may be detected and afterwards corrected.
