Abstract:
1. An amplifying device comprising: a signal separating unit that separates a first signal and a second signal from an input signal; a first signal-generating unit that generates, based on the first signal, a first cancelling signal that can suppress ringing caused during processing of the first signal; a first combining unit that combines the first signal and the first cancelling signal; a first amplifying unit that amplifies a signal output from the first combining unit; a second signal-generating unit that generates, based on the second signal, a second cancelling signal that can suppress ringing caused during processing of the second signal; a second combining unit that combines the second signal and the second cancelling signal; a second amplifying unit that amplifies a signal output from the second combining unit; and a third combining unit that combines a signal output from the first amplifying unit and a signal output from the second amplifying unit.
