Title:
ANALOG SIGNAL PROCESSOR
Document Type and Number:
Japanese Patent JP3956383
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize an analog signal processor in which the number of components can be reduced, and any offset voltage due to the detection of discontinuity can be eliminated.
SOLUTION: This improved analog signal processor for inputting analog signals from a plurality of signal sources is provided with a selecting part for selecting a plurality of signal sources; an A/D converter connected to signal lines from the selecting part for converting the analog data into digital data; a discontinuity detecting power source for outputting currents to the signal lines of the selecting part and the A/D converter; and a phase control part for controlling the selecting part to select the signal sources, and for separately executing the conversion of the signals of the signal sources by the A/D converter and the impression of the currents of the discontinuity detecting power source.
