Abstract
PURPOSE: To enhance the reliability by deciding the code or the noise for the peak pulse which is detected within a fixed period from the peak pulse exceeding the threshold level and does not exceed the threshold level via the pulse detected thereafter.
CONSTITUTION: The positive peak pulse exceeding the threshold level is obtained at output 36 of gate 10; while the negative peak pulse exceeding the threshold level is obtained at output 37 of gate 11 respectively. One-shot circuit 13 is triggered by output 36 and reset by output 37. In order words, the sampling is given via circuit 13 to the peak pulse which arrives in a fixed time after output 36 and does not reach the threshold level to turn the peak pulse to output 41. Furthermore, one-shot circuit 41 is triggered, and output 42 is applied to gate 18 for sampling positive peak pulse 36 after output 42. Thus the peak pulse due to the noise can be eliminated.
