Title:
VECTOR SIGNAL PROCESSING CIRCUIT
Document Type and Number:
Japanese Patent JP3675256
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a vector signal processing circuit which is small in power consumption and can be constituted at a low cost.
SOLUTION: Three axial signals of a sensor are rectified by full-wave rectifying circuits 4 each formed by combining four diodes and their outputs are added by an adding circuit 5, whose output is converted into a digital signal through a comparator 6. Diode forward voltage drop characteristics of the rectifying circuits 4 are 0.3 V and the threshold of the comparator 6 is 0.6 V.
