Program Discriminating Electronic Tuning Car Radio

A successful development was achieved of a car radio with an electronic tuning system which is provided with such an entirely novel function as continuous automatic selection of the broadcasting station with the highest receiving level among identical programs by directly comparing the receiving sound signals of the broadcasting station with those of other stations.

It is particularly epoch-making that this development was realized with a 1-tuner system, since it was thought very difficult to achieve such a development with a 1-tuner system. The practical value of this development could be also confirmed.
