GHOST CANCELLATION DEVICE

摘要

TITLE OF THE INVENTION: Ghost Cancellation Device Disclosed is a device for cancelling the ghost signal wherein at least two antenna bays are spaced apart in the horizontal direction by 1/4 wavelength, a mixer is provided which mixes the outputs from the antenna bays, phase shifter for shifting the ghost signal in phase with or out of phase by 180.degree. with the desired signal is inserted between the output terminal of one antenna bay and an input terminal of the mixer, amplitude controller is inserted between the output terminal of the other antenna bay and an input terminal of the mixer, and the output from the mixer is delayed and the delayed output and the direct output from the mixer are mixed so as to control their amplitudes and polarities, whereby the ghost signal may be cancelled.
