<p><P>PROBLEM TO BE SOLVED: To provide a measuring unit for suppressing high-frequency radiation noise occurring from an insulated element and the other signal transmission system, and a unit attachable/detachable instrument having the measuring unit. <P>SOLUTION: In this measuring unit, a measuring circuit includes a signal converting means for converting an analog signal into a digital signal based on a first clock signal and a synchronizing signal of a sampling clock, a clock signal generating means for generating a second clock signal having the same cycle as the synchronizing signal of the sampling clock, in which each cycle includes at least one clock pulse, from the first clock signal, a digital signal processing means for receiving the digital signal and the second clock signal via the insulated element, demodulating the second clock signal into the same frequency as the first clock signal, and further applying digital processing to the digital signal based on the second clock signal. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
