Integrated Circuits in Television Receivers

To evaluate the significance of integrated circuits in television receivers, the 4.5-MHz intercarrier sound channel was integrated on amonolithic silicon chip. Use of this chip in production monochrome and color television receivers has resulted in improved performance, greater reliability, and potentially lower cost. From the experience gained in this project, it is estimated that some 20% of the chassis component cost of a television receiver is susceptible to economically-sound use of integrated circuits. It appears that the television circuit-design engineer is best equipped to take the initiative in the design of integrated circuits because of the complexity of the integrated circuit-receiver interface. Considerations in the specification and testing of integrated circuits are described.
