    摘要: This disclosure relates to a signal processing device, a signal processing method, and a receiving device that are capable of detecting response information at a high degree of accuracy from a carrier signal that is load-modulated based on the response information. A positive DC generating unit 61 generates a positive threshold based on a load-modulated carrier signal. A positive selecting unit 62 compares the voltage of the carrier signal with the positive threshold, and outputs the value of the larger one to an adding unit 65. A negative DC generating unit 63 generates a negative threshold based on the load-modulated carrier signal. A negative selecting unit 64 compares the voltage of the carrier signal with the negative threshold, and outputs the value of the smaller one to the adding unit 65. The adding unit 65 adds the output of the positive selecting unit 62 and the output of the negative selecting unit 64, and outputs the addition result to an IQ detecting unit 53. As a result of the combining, a signal that has smaller Vpp than that of the original carrier signal and maintains the fluctuation portions of the voltage is obtained. This disclosure can be applied to non-contact communication systems.

    摘要: A communication apparatus includes a signal detector that detects incoming (i.e., receives) information from a signal received wirelessly. The signal detector includes a wave detector, an equalizer, and a detector. The wave detector accepts an incoming signal wherein information is modulated onto a carrier signal, analyzes the envelope variation of the incoming signal, and generates a detection signal containing the incoming information. The equalizer corrects the detection signal and outputs a corrected detection signal. The detector then detects the incoming information from the corrected detection signal.

    摘要: First, data is read from tracks formed on a tape-shaped recording medium by heads disposed on a rotary drum, to measure error rates. Next, of the tracks formed on the tape-shaped recording medium, a worst track suffering the highest error rate is detected based on the error rates thus measured. Then, a pair of reproducing heads that can reproduce the worst track thus detected at the lowest error rates is detected from the measured error rates. Thereafter, tracking servo control is performed such that the worst track can be scanned by the pair of reproducing heads. As a result, a reproducing apparatus capable of proper reproduction even when recorded tracks undergo variations in width and reproducing heads are erroneously mounted.
