Electronic radios and hi-fi sound

The development by the Semiconductor industry of large scale MOS integrated circuits, hyperabrupt junction tuning diodes, digital displays and high speed digital circuits have made possible the development of electronically tuned automotive radios. The market environment created by digital clocks and watches and by digital calculators has led to the warm market reception of electronically tuned automotive radios. The introduction of FM stereo broadcasts, tape players, noise reduction circuits, noise blanker circuits, stereo/mono blend circuits, improved tapes, audio power booster amplifiers, graphic equalizers, and improved speakers have all contributed to the development of automotive hi-fi sound. Today´s youth, who were raised in a home hi-fi environment, have been the driving force in the automotive hi-fi marketplace. With electronically tuned automotive radios and automotive hi-fi sound in its infancy, it is more likely that the future will bring improved performance in both the broadcast and recorded audio functions. These performance improvements must be made in concert with the other improvememts dictated by the changing automobile market. The future market will likely become more sophisticated requiring higher product performance and modified selling techniques.
