PURPOSE:To obtain the signal reception circuit in which the effect of chattering or ringing in a long consecutive time is completely eliminated even when the chattering or ringing for a long consecutive time is included in an inputted digital signal. CONSTITUTION:The intermediate signal C of an EXOR 1 rises by the first leading of an input signal A from an input terminal 53 and a pulse signal D in a prescribed time constant is generated from a monostable multivibrator OS2. A delay signal B is obtained from a TFF 3 with the trailing of a pulse signal D and returned to the other terminal of an EXOR 1 and the intermediate signal C falls down. The operation is similarly implemented even in the case of a trailing of the input signal A. On the other hand, the delay signal B is latched by a DFF 4 at the leading of a pulse signal (d) and the result is led to an output terminal 54 as an output signal E in phase to the input signal A. |
