PURPOSE:To attain accurate receiving, by comparing an input signal with a delayed signal in a digital signal receiving circuit. CONSTITUTION:The input signal applied to an input terminal 10 is branched into three signals; one is amplified 1 as it is, other is amplified 4 (double amplication factor of that of an amplifier 1) after a delay 2 by T1, and the rest is amplified 5 (the same amplification factor as the amplifier 1) after a delay 3 by T2. The T1 and the T2 have the relation of T1<T2<Tmin, where Tmin is the minimum pulse width of the pulse. The three branched signals are compared at comparator circuits 6, 7, ANDed 8 and a waveshaped output is obtained at a terminal 11. |
