Abstract
An electronic switch used in a low-noise block down converter for receiving satellite horizontal or vertical polarization signals. The electronic switch only needs one single wire to receive a pulse width signal of a TV receiver. The electronic switch output a HIGH voltage level and a LOW voltage level according to the pulse Width of the signal from the TV receiver to control the selection of the vertical or horizontal polarization signals.
