PURPOSE:To obtain a circuit suitable for circuit integration by applying sampling after a reception signal is subject to binary quantization, and applying comparing and detecting to each value subject to integration while being added with a proper weight signal so as to facilitate digital signal processing. CONSTITUTION:A reception signal inputted to an input terminal IN from a transmission line is subject to elimination of noise component at the outside of a required band at a reception filter 1, the correction of distortion and waveform shaping generated in the transmission line are applied and the result is inputted to a binary quantization circuit 2. The obtained data is inputted in parallel to multiplication circuits 4, 5, 6, 7 sequentially. On the other hand, a weight signal is outputted from weight signal generating circuits 8, 9, 10, 11 and inputted to the multiplication circuits 4, 5, 6, 7. The content of registers 16, 17, 18, 19 is compared just before the content of the said register is reset by a digital data comparator circuit 20 is reset and a number of a weight signal generating circuit corresponding to the register representing a maximum value among the four registers 16, 17, 18, 19 is outputted from a digital data compari son circuit 20 as a result of identification of reception signal. |
