摘要： A motor control device that controls the driving of a motor having a permanent magnet provided at a rotor has: an angle detector that detects the angle of the rotor by use of an angle sensor; a current detector that detects, as a detected current, the outflow current from or inflow current to a direct-current power source serving as the source for driving the motor; and an angle corrector that corrects the detected angle based on the detected current. The driving of the motor is controlled by use of a corrected angle obtained through the correction by the angle corrector.

摘要： A high frequency compensator includes a down sampler configured to perform ½ down-sampling for a compressed and expanded digital audio signal. An up sampler is configured to perform double up-sampling for an output signal of the down-sampler. A digital low-pass filter is configured to filter an output signal of the up sampler. A digital high-pass filter is configured to filter an output signal of the digital low-pass filter. An adder is configured to add an output signal of the digital high-pass filter to the compressed and expanded digital audio signal, and to output a digital audio signal generated by the adding.
