发明名称 Transmission output correcting apparatus
摘要 A first control unit reads out both specific frequencies and gain data corresponding to these specific frequencies, which have been stored into a first storage unit, and approximates gain data corresponding to an arbitrary frequency by way of a linear function to calculate the gain data by executing a formula. A D/A converter converts this gain data into a gain control signal, and supplies the gain control signal to a variable gain amplifier. The variable gain amplifier amplifies a transmission signal by a gain defined in response to a transmission frequency based upon the gain control signal.
