DEVICE AND METHOD FOR EXTRACTING AMPLITUDE INFORMATION

摘要

PROBLEM TO BE SOLVED: To provide an amplitude information extracting device capable of reducing an amplitude error with a circuit scale smaller than that of a logical operation circuit.

SOLUTION: This amplitude information extracting device 110 acquires amplitude information (amplitude value Z') corrected from I components and Q components of a transmission signal. A phase information extracting device 111 acquires phase information from the I components and the Q components of the transmission signal. The amplitude information extracting device 110 corrects the acquired amplitude information (amplitude value Z') on the basis of the phase information acquired by the phase information extracting device 111 to acquire an amplitude value Z.
