Abstract

PURPOSE:To reduce the production of click noise due to the difference of reception level at switching, by detecting the reception level of two reception systems and the level difference to be a fixed value or less. CONSTITUTION:Level detectors 13, 14 detect the reception level, the 2nd comparison circuit 16 inputs the level signal of the detectors 13, 14, the level comparison and the comparison of the level difference and the set value are made to switch the change-over switch 10. Between two reception system, the reception system with small distortion level and great reception level is selected, and if the reception level difference exceeds the set value, the reception system with great reception level is selected.
