  • Publication number: 20100150362
    Abstract: According to one embodiment, an acoustic apparatus comprises a measuring signal generator, a transducer configured to convert a measuring signal to a measuring sound and to convert a characteristic vibration of the transducer due to the measuring sound, to a characteristic vibration signal, an analysis module configured to analyze the characteristic vibration signal in order to output a physical quality of a characteristic vibration of the transducer, a controller configured to set a first state in which the transducer converts an electric signal to an acoustic signal or a second state in which the transducer converts an acoustic signal to an electric signal. The measuring signal generator is connected to the transducer in the first state and the analysis module is connected to the transducer in the second state.

  • Publication number: 20080019249
    Abstract: An apparatus for reproducing digital data recorded on a recording medium by a Partial Response Maximum Likelihood method, the digital data being recorded in a code pattern in which the same code continuously appears at least two times, includes an analog-to-digital converting unit that samples an analog reproduction signal recorded on the recording medium and converts the sampled analog reproduction signal into a digital signal; a sampling rate switching unit that adaptively switches the sampling rate in the analog-to-digital converting unit from a higher rate to a lower rate; and a data demodulating unit that reproduces and demodulates the digital signal subjected to the analog-to-digital conversion in the analog-to-digital converting unit by the Partial Response Maximum Likelihood method in accordance with the switching between the higher rate and the lower rate.
