ABSTRACT:
A transmission measuring system includes a subject for transmission measurement for outputting, in response to a start signal for measurement from a central processing unit, an output signal including information on a transmission time to be measured. An analog-digital converter converts the output signal into digital data. The central processing unit processes the digital data to obtain the transmission time required for propagating the signal through the subject. A clock signal source provides a clock signal to the central processing unit, and a variable delay unit is interposed between the clock signal source and the analog-digital converter. The central processing unit delivers a delay time control signal to the variable delay unit so that the delay time of the clock signal of the analog-digital converter may be varied with time relative to the start signal for measurement.
