Abstract

PURPOSE: To make it possible to switch signals in a high speed with a simple circuit constitution by connecting commonly output terminals of plural input signal transmission lines to a high input impedance amplifier to supply input signals to this amplifier.
CONSTITUTION: Input protection resistances 3a...3n are connected to input signal transmission lines 2a...2n, and capacitors 14a...14n are connected between lines 2a...2n in the output side of resistances 3a...3n and the earth, and signal switching electronic switches 5a...5n are provided in the output side of capacitors 14a...14n. Then, output ends of lines 2a...2n are connected commonly and are connected to high input impedance amplifier 6, and input signals are sent to amplifier 6 from lines 2a...2n selectively. As a result, signals can be switched in a high speed with a simple circuit constitution.
