APPARATUS FOR CAPTURING SIGNAL SAMPLE TO ACQUIRE ACCURATE INFORMATION WITHOUT DEPENDING ON EXPENSIVE TECHNIQUE

摘要

PURPOSE: An apparatus for capturing a signal sample to acquire accurate information without depending on an expensive technique is provided to improve the accuracy of removing distortion without increasing the cost for a distortion control mechanism. CONSTITUTION: A sampler samples wave form part of the first and second signals. A switch(32) alternates connection of the sampler to a point in a device where the first signal is sampled and to another point in the device where the second signal is sampled. A timer timing operation of the switch(32) to sample a first wave form part of the first signal, and the second wave form part of the second signal, wherein the second signal responses to the first signal. The timer is arranged to use electric waves between the points to include a part generated by the second wave form part responding to the first wave form part.
