IPC: H04B3/06
Filed: 1984-05-24
Abstract: PURPOSE:To equalize properly a flat loss easily with simple constitution by extracting a signal required for compensating the flat loss from a burst signal transmitted from the transmission side to control a flat gain amplifier. CONSTITUTION:A reception information signal S1 of the burst mode received to an input terminal 100 is inputted to a flat gain amplifier section 11 and a supervisory signal extracting section 22. The extracting section 22 extracts at least one supervisory signal from the signal S1 and inputs it to a flat gain control section 21. The control section 21 compares the input supervisory signal with a prescribed value and outputs a control signal so that the gain corresponding to the said difference is compensated by the amplifier section 11. The amplifier 11 outputs an information signal S2 where the flat loss is equalized and it is inputted to a slope gain amplifier section 31. A slope gain control section 41 inputs an output information signal S3 of the amplifier section 31, controls the gain of the amplifier section 31 so that the signal S3 is a prescribed amplitude based thereupon and converges the slope loss so as to be equalized properly.
