Abstract: A controller switches between modes each having a different connection state of a DC power supply and the capacitor with respect to first and second output points by controlling switches. A generation unit generates a reference wave including at least one carrier wave. The modes are classified into a sustaining mode in which no current is caused to flow to the capacitor, a charging mode in which a current is caused to flow to the capacitor, and a discharging mode in which a current in a direction opposite to that in the charging mode is caused to flow to the capacitor. The controller switches between the sustaining mode and a charging or discharging mode according to the comparison result between a signal wave and the reference wave.

Abstract: Even if contents data distributed over a network are once destroyed, the contents data are restored, as the copyright protection is maintained. A PC memorizes backup of distributed music contents on a hard disc, at the same time as it transmits the using log information of the music contents stored in the hard disc to an EMD server. If the music contents in the hard disc are destroyed, the PC acquires the using log information from the EMD server to reproduce the backup data memorized in the hard disc depending on the using log information.

Abstract: A transmitter providing a wide output control variable width with high efficiency is provided. Saturation mode operation is performed in the vicinity of the maximum transmission power and the input level of a large power amplifier is enlarged and fixed. When the large power amplifier is operated in a saturation state, the amplitude component of a modulation signal is input to an R input terminal in the range responsive to an output power control level and power supply voltage of a power supply terminal is amplitude-modulated, whereby highly efficient polar coordinate modulation is performed. In smaller transmission power, linear mode operation is performed, the input level of the large power amplifier is lessened for operating the large power amplifier in the linear mode, and the power supply voltage of the power supply terminal is made variable in response to the output power control level, whereby transmission power control is performed.

This transmitter comprises an amplitude delay corrector and a phase delay corrector capable of correcting delay time so that the phase and amplitude components are optimally synthesized using two or more stages of saturation-type amplifiers constituting the high-frequency power amplifier.
