Abstract
PURPOSE:To facilitate an easy integrated formation for the circuit which obtains the difference between the input signal and the signal obtained by giving a fixed delay to the input signal by simplifying the circuit constitution and also reducing the number of the outside draw-out pins in the case of the constitution of an intergrated circuit. CONSTITUTION:Electromagnetic delay line 60 is used as the delay means, and one terminal of the delay line is connected to the short-bar with the other terminal connected to output terminal 65 as well as to input terminal 66 via resistance 61. The value of resistance 61 is selected identical to the characteristic impedance of line 60, and the short-bar terminal of line 60 is put under the complete reflection with the other terminal put under the non-reflective state each. Line 60 of the differential circuit of such constitution is composed of the coaxial cable, and the input signal is used for the TV picture receiver in the form of the video signal of the TV picture receiver containing the ghost. Then the capacitor featuring such capacity as to offset the zero caused by the feed-through connected at the connection part between resistance 61 and delay line 60 is provided, and thus the differential signal between the input signal and the signal caused at the connection part between 61 and 60 is delivered.
