摘要：A transmitting circuit apparatus has a first digital modulator and a seconddigital modulator for modulating an I signal and a Q signal which are multi-valued digitalbaseband modulation signals, into a digital I signal and a digital Q signal, respectively,having the number of bits smaller than that of the baseband modulation signals; and aquadrature modulator for outputting a signal synthesized from the signals generated bymodulating (two) carrier waves each having a phase perpendicular to each other by usingthe modulated I and Q signals, respectively.
