摘要： A differential amplifier circuit is connected to the input node and the output node of the final amplification stage through detection circuits. The signal level difference output from the differential amplifier circuit does not change even if the input power varies. Because a change in the power gain at the output node does not travel back to the input node when the load impedance of the wireless frequency power amplifier varies, it is possible to detect only the change in the load impedance. Damage to the final stage can be prevented by controlling the operating current of the final stage and the gain of the drive stage according to the detected load variation. Nonlinear distortion in the wireless frequency power amplifier output can also be reduced by detecting and canceling the change in the gain of the drive stage by changing the gain of the adjustment stage.

摘要： An information providing method and apparatus in which a radio wave signal is transmitted from plural artificial satellites and received at plural receiving equipment located within a pre-defined service area, and receiving within a pre-defined range of operational elevation angle by a receiving antenna. The plural artificial satellites are viewable in turn within a pre-defined range of operational elevation angle at an arbitrary location within the pre-defined service area, and an orbit is arranged so that at least one artificial satellite is viewable. Each orbit of the plural artificial satellites is arranged on an individual orbital plane according to a designated service hour. The individual orbit is located in a range where an orbital inclination angle is 63.4 degrees or closer to Japan, and a right ascension of a north-bound node of the individual artificial satellite is separated approximately at regular intervals.

摘要： Disclosed is a digital demodulation technique in which a reception modulated-wave signal is converted into a digital signal in synchronism with a sampling frequency, whereafter carrier regeneration/detection is carried out upon the digital signal to thereby output a detection signal. Then, the detection signal is subject to interpolation and resampling on the basis of a clock frequency established asynchronously with and independently of the sampling frequency, so that a timing component is extracted from the detection signal in synchronism with the clock frequency to thereby output a reception data. In the digital demodulation technique, since the sampling frequency and the clock frequency are established asynchronously with and independently of each other, jitter or the like produced in clock regeneration do not affect the carrier regeneration/detection. Consequently, noiseless reception data with little jitters can be regenerated.
