Title:
PROCESSING CIRCUIT AND SIGNAL CORRECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/140976
Kind Code:
A1
Abstract:
The present invention is provided with: a transmission circuit (102) that is mounted on a printed circuit board (150), has attenuation characteristics, attenuates the amplitude of a received signal (1001) in accordance with the attenuation characteristics and outputs the result as an attenuated signal (1002); and a correction circuit (103) that is mounted on the printed circuit board (150), has correction characteristics, attenuates the attenuated signal (1002) received from the transmission circuit (102) in accordance with the correction characteristics and transmits the result as a corrected signal (1003). The attenuation characteristics are such that the ratio of the amplitude of the attenuated signal (1002) to the amplitude of the received signal (1001) decreases as the frequency of the received signal (1001) increases. The correction characteristics are such that the ratio of the amplitude of the corrected signal (1003) to the amplitude of the attenuated signal (1002) increases as the frequency of the attenuated signal (1002) increases.
