Abstract
PURPOSE:To prevent the deterioration of a signal due to upfading by providing a level limiting means, operating in response to a reception input, in front of an amplifying means. CONSTITUTION:An input signal from terminal 1 is applied to input level detector 8, which when its value is large, sends an output to input level control part 9 and input level limiting part 10 limits the input level. The output of limiting part 10 is amplified by amplifiers 2-4 and some of their outputs are applied to output level detection part 6. The output of detection part 6 is sent to output level control part 7 to control gains of amplification parts 2-4.
