摘要

PROBLEM TO BE SOLVED: To prevent influence between signals due to load fluctuation at the time of gain switching in a system having a plurality of processing systems. SOLUTION: A gain adjusting means provided for the number of input signals and adjusting a gain value used for signal amplification and a signal affecting the signal level of another signal are different from the other signals. The gain reflection control means for changing the switching timing of the gain value in the gain adjusting means is provided so that the gain value is switched during the period of.
