Filter adjusting apparatus, power adjusting system, and filter adjusting method

摘要

According to one embodiment, a filter adjusting apparatus comprises a reference signal generator (104) configured to generate a reference signal having an amplitude set by an amplitude control signal, a setting module (105) configured to set different filter characteristics to the filter, and to set different amplitudes of the reference signal, an amplitude detector (107) configured to detect amplitudes of a filter output with reference to the reference signal having the different amplitudes, and a determining module (112) configured to determine a desired characteristic control signal in accordance with the amplitudes detected by the amplitude detector.
