Modem Device And Amplitude Adjustment Method

Abstract: Provided is a modem that can process a signal output from a demodulator without being affected by frequency conversion noise and an amplitude adjustment method. The disclosed modem is provided with: a modulator (12), which generated a modulated signal from a transmission signal; a frequency converter (15), which generates an intermediate frequency signal from an external input signal that is input from an external device (50); and a demodulator (14), which demodulates a modulated or intermediate frequency signal and generates a reception signal.
