Cardiotachometer and frequency meter in fact belong to one sort of measure instrument. The difference is that the time gate of cardiotachometer is 1min, but not 1s. As to one measure instrument, measuring time of 1 min is long and hard to guarantee the precision. Therefore, alternate measuring is necessary, which meets the requirement of quickness and precision.The aboved picture is cardiotachometer circuit, and it can match the requirement of quickness and precision.
