摘要： A radio communication apparatus is designed for a plurality of different radio communication formats, one of which can be selected. The radio communication apparatus includes a fixed-gain IF amplifier and a variable-gain IF amplifier. One is selected out of the fixed-gain IF amplifier and the variable-gain IF amplifier as an effectively used IF amplifier in response to which of the radio communication formats is selected. The fixed-gain IF amplifier is selected as an effectively used IF amplifier when a narrow-band radio communication format is selected. The variable-gain IF amplifier is selected as an effectively used IF amplifier when a wide-band radio communication format is selected.

摘要： An automatic frequency controller synchronizes a received carrier signal with a simulated carrier signal to automatically control a center frequency of the simulated carrier signal. The received carrier signal has a first synchronous code pattern inserted into a plurality of frame periods and a second synchronous code pattern inserted into a plurality of multiframe periods. The phase of the received carrier signal is determined by sweeping the center frequency of the simulated carrier signal and mixing the simulated carrier signal with the received carrier signal. The sweep of the center frequency of the simulated carrier signal is reduced when frame synchronization is detected and the sweep of the center frequency is fixed when multiframe synchronization is detected.

摘要： Load sharing rates of an internal combustion engine and an electric motor of a hybrid powered vehicle are definitely controlled to improve fuel efficiency of the vehicle during an auxiliary running with using power of the electric motor together with power of the internal combustion engine when a pressing amount of an accelerator pedal of the vehicle is small. In response to a pressing amount information of the accelerator pedal inputted to a hybrid control circuit, the hybrid control circuit calculates the load sharing rates of the internal combustion engine and the electric motor by referring to a preliminarily set control map and controls the motor according to its load sharing rate. The hybrid control circuit sends an electric signal corresponding to the load sharing rate of the internal combustion engine to the internal combustion engine control circuit, instead of the pressing amount information of the accelerator pedal.

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.

摘要： A radio communication apparatus is designed for at least first and second radio communication formats which prescribe first and second desired IF pass bandwidths respectively. The first desired IF pass bandwidth is greater than the second desired IF pass bandwidth. The radio communication apparatus includes an IF band-pass filter processing a first IF signal into a second IF signal and having a predetermined pass bandwidth corresponding to the first desired IF pass bandwidth. A demodulator recovers a first baseband signal from the second IF signal generated by the IF band-pass filter. A baseband filter processes the first baseband signal generated by the demodulator into a second baseband signal. The first baseband signal generated by the demodulator is selected as a final output signal when the first IF signal is of the first radio communication format. The second baseband signal generated by the baseband filter is selected as a final output signal when the first IF signal is of the second radio communication format.
