Threshold correction circuit, circuit and threshold correction function with circuit board

摘要

As for this invention, high-speed transmission and doing the small amplitude conversion of the signal low for electrical conversion with the automatic operation adjustment of the threshold for monitor of various noises which the signal in the signal conductor on the circuit baseplate receives, and considers signal state distinction influence of that noise which as possible, in order to try to be able to do signal state distinction securely without receiving the influence of various noises, the signal formation department which forms the noise monitor signal (12) with, being input the aforementioned noise monitor signal, the noise monitor signal conductor which is spread (5) and this noise monitor signal conductor (5) the description above which is spreadBeing the noise which is recorded before the noise monitor signal, in order for signal state distinction not to receive the influence of the aforementioned noise when it detects the aforementioned noise the noise sensing station which detects the noise which produces effect on the signal state distinction which uses threshold (13) with, this noise sensing station (13) with, the threshold adjustment section which adjusts the aforementioned threshold (14) with having, it constitutes.
