PURPOSE:To halve a substantial sampling interval, by using two lines which transmits a signal at a specified interval while shifting the transmission interval mutually and transmitting the sampling signal from one signal source through the use of the two lines alternately. CONSTITUTION:A sampling signal from a signal source consisting of car sensors D1-D4 is transmitted by using two lines L1, L2 alternately. That is, an oscillator 11 is controlled for start with an output of an oscillator 5 via a delay line 17, and the output is delayed by 50msec. compared with the output of the oscillator 5. Thus, the 1st and 2nd counters 3, 4 have a time shift of 50msec., and a sample signal of the car sensors D1-D4 is transmitted from the lines L1, L2 at every 100msec. by the output of the respective counters 3, 4. Thus, as to one car detection signal, it is alternately transmitted from the two lines L1, L2 with 50msec. shifted, then substantial sampling speed can be 50msec. |
