PURPOSE:To realize the shortest-course selection of the target pulse train in case the central frequency of the pulse train is set equidistantly and only the target pulse train is selected, by giving a parallel inspection to the pulse train to be supplied. CONSTITUTION:In case the target pulse train 8 is mixed with the two types of disturbance pulse trains 9 and 10 to be the adjacent periods of the pulse train 8 at the input terminal 6. These pulse trains are first put into the monostable multivibrator 1 that shapes the input pulse duration to a certain value to obtain the waveform (a). Then the clock pulse is applied from the clock pulse generator 2, and the waveform (a) is shifted (waveform d) by a certain bit via the shift register 3. This waveform (d) is applied to the monostable multivibrator 4 which produces the gate pulse to obtain the gate pulse (waveform e). Then the normal signal output (f) is obtained through the AND circuit 5 and by utilizing the nature in that the normal signal 8 emerges equidistantly. |
