Abstract
A digital signal receiver capable of obtaining a favorable receiving performance even if the input signal level changes rapidly is presented. A control voltage for controlling a variable gain amplifier is read by a microprocessor, and an operation-starting point of the variable gain amplifier is shifted by using this control voltage. As a result, a favorable level fluctuation response characteristic is obtained regardless of the input level.
