Abstract
PURPOSE:To prevent an effect of noise during a short-cycle clock, by securing a start of time limiting action by either a rise or a fall of the clock pulse with use of a delaying circuit having a delay time shorter than the data cycle. CONSTITUTION:A monostable multivibrator 1, which receives the transmitted clock pulse and is triggered by either a rise of a fall of the clock pulse, is shorter than the data cycle Td. A sampling circuit 2 receives the output of the vibrator 1 and the transmitted data and samples the data when the metastable state of the vibrator 1 ends to hold the data until the next sampling. When the clock and data are transmitted with inclusion of noise via a circuit, the output is set at a high level for the metastable time that is set previously at the final edge of the clock.
