Abstract

PURPOSE:To secure an effective deletion of the ghost generating at the TV picture receiver by constituting the disturbing wave deletion device with two antennas provided on the equal wave surface, the phase shifter, the sum circuit and the differential circuit each. CONSTITUTION:Two units of antennas 1 and 2 are provided so that they may be the equal wave surface to the desired wave and different in the propagation wave length to the disturbing wave, and output S1 of antenna 1 is supplied to sum circuit 32 as well as to sum circuit 31 via pi/2 phase shifted 21. While output S2 of antenna 2 is also supplied to circuit 31 as well as to circuit 32 via pi/2 phase shifter 22. Then composite signal S31 obtained through circuit 31 is supplied to sum circuit 23 and differential circuit 33, and composite output S32 obtained from the output of circuit 32 is applied to circuit 33. After this, outout (S31 -S 32) of circuit 33 is supplied to circuit 23 via pi-phase switch 40 and variable attenuator 50, and the signals sent from output terminal 24 are applied to the TV receiver.
