Abstract

PURPOSE:To confirm the adjustment of delay time, by applying FM and AM detection signals delayed with each delay device delaying the FM and AM detection output signal and a delay device of 1/2 delay time, to a plane drawing display device. CONSTITUTION:A multipath distortion reducing device is provided with a variable delay device 13 delaying an output of an FM detector 7, and variable delay device 11 delaying an output of an AM detector 10 detecting an AM modulation component due to direct and reflected waves of a reception signal by the same time as the delay device 13, and variable dealy device 20 of a half delay time as both delay devices. If the direct wave is greater than the reflected wave, switches 16-19, 21-25 are connected to a contact 1, and an AM detection output and an FM detection output delayed at the delay device 20 are applied to terminals 27, 28 of a plane drawing display device 26. If the reflected wave is greater than the direct wave, the switches 16-19, 21-25 are connected to a contact 2, and the AM and FM detection outputs delayed at the delay device 20 are applied to the terminals 27, 28, to confirm if the adjustment of each delay device is complete by the display device 26.
