<p>PURPOSE:To obtain a simple circuit which does not distort a weak signal from a point at a long distance and can operate an STC having a large dynamic range for a sampling receiver. CONSTITUTION:The receiver has a switch circuit 7 is provided in the preceding stage of a high-frequency amplifier 8 so that only the signals within the time zone required for sampling can be amplified by generating a gate signal from a strobe signal used for sampling and turning on/off the switch circuit 7 by means of the gate signal.</p> |
