APPARATUS FOR IMPROVING RESOLUTION OF ANALOG/DIGITAL CONVERTER

摘要

PURPOSE: Apparatus for improving the resolution of an analog/digital converter is provided to improve the resolution of an analog signal inputted from an outside without using an additional analog/digital converter. CONSTITUTION: A plurality of amplifying section(10) amplifies voltage signals with predetermined ranges to improve the resolution of an inputted analog signal. A multiplxor(20) selectively transmits a plurality of the input signals and an original signal of a treated signal through a single transmission path. An analog/digital converter(30) converts the original signal and the treated signal transmitted from the multiplxor(20) into digital signals. A controlling section(40) produces a signal for improving the resolution by assembling the digital signal of the original signal and the treated signal.
