This chapter has outlined the incorporation of both analogue and digital circuits in a single chip to meet stringent technical and economic requirements of a video communications application. Such a hybrid approach is becoming very important for many applications in the telecommunications area, such as modems, radio-telephones and ISDN equipment in general. To obtain the maximum benefit from this approach, analogue and digital parts can not be synthesised and analysed separately but a unified approach will be found to be the best. This will result in the development of many specific mixed mode techniques in the future.
