    摘要: A ladder-type electric filter device having rubber plates each provided on one or both sides of each of the piezoelectric resonators so as to be brought into resilient contact with the surface of the associated piezoelectric resonator. The rubber plates are shaped so as to not be brought into contact with the respective corner edges of the respective piezoelectric resonators which generate extensive contour vibrations. Thus, the contour vibrations are not suppressed, the insertion loss can be reduced, and a mechanical quality factor Q can be substantially decreased, thereby improving group delay frequency characteristics.

    摘要: A musical tone synthesizing apparatus comprising FM operators and connection control device. At least one of the FM operators comprises a waveform memory, phase data generation device, and output inversion device. The waveform memory stores fundamental waveform data. The phase data generation device generates phase data as an address signal for accessing the waveform memory on the basis of a musical tone designation signal and a modulation signal inputted from an external circuit. The output inversion device selects whether a waveform signal read out from the waveform memory is outputted after sign inversion, or is outputted directly. The connection control device arbitrarily combine connections of the FM operators.

    摘要: A signal transmission system has a modulation signal converter 1 that generates a modulation signal using a Manchester code with a duty ratio of 50% in accordance with transmission data; a clock generator 6 that generates a clock with the amount of delay with respect to the rising or falling edge of the modulation signal; and a data detector 5 that generates received data by sampling the modulation signal in synchronization with the clock. Since the modulation signal converter 1 generates the modulation signal by combining the Manchester code with the duty ratio of 50%, its duty ratio is always 50% independently of the transmission data, thereby preventing the DC offset of the modulation signal on the receiving side. Accordingly, it offers an advantage of achieving good communication quality with a simple circuit configuration without producing the DC offset in the modulation signal on the receiving side.
