Abstract
PURPOSE: To eliminate trouble of channel selection by making it possible to switch automatically a receiving broadcast to an optimum broadcast when the receiving level is lowered in the receiving time of broadcast of a certain broadcast station.
CONSTITUTION: Signals indicating receiving levels are obtained for every receiving frequency from detection circuit 21 according to change of receiving frequencies and are converted to digital signals Qd and are supplied to comparator circuit 35. Receiving level Qm before change and Qd are compared with each other, and Qd is written in memory 34 in case of Qd>Qm. When memory 34 becomes a write mode, value n of counter 29 at this time is written in memory 33, and value n for broadcast of the maximum receiving level is written in memory 33. Then, the output of timer circuit 23 is obtained at every fixed time, and another station is received in case that the level of this station is higher than the receiving level of the current receiving station by movement of a vehicle, etc.
