Title:
SIGNAL PROCESSOR
Document Type and Number:
Japanese Patent JP3518738
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a signal processor that can effectively and precisely process input signals even they are two-phased or single-phased in a signal processor capable of processing input signals considered to be object of signal processing by converting the signals into signals having four phases to the most.
SOLUTION: An expanding and reducing section 2 is provided with expanding and reducing circuits 21 to 24. When single phase signals are inputted, a selection section 1 supplies the signals to all circuits 21 to 24. When two phase signals are inputted, one of the two phase signals are supplied to the circuits 21 and 22 and the other phase signals are supplied to the circuits 23 and 24. When four phase signals are inputted, the signals are supplied to the respective circuit 21 to 24.
