    摘要： In a null symbol detection device, at the time of receiving a terrestrial digital broadcast, a null symbol can be stably detected even under a fading environment. A synchronous addition buffer group is provided subsequent to an amplitude detector so as to synchronously add an OFDM signal at a null symbol repetition period. A moving average processing unit performs a moving average operation upon synchronous addition data with the number of samples corresponding to a null symbol to output a moving average value. A transmission mode determining unit detects the minimum value among the moving average values normalized in a correction processing unit and compares levels of the minimum values to determine a reception mode. A null position detector generates a synchronous pulse at a null position.

    摘要： An array microphone is a directional microphone having an improved directional characteric in which both the sensitivity and the sound pressure frequency response are uniform within the recording area and more particularly, the quality and level of sound remain unchanged. The array microphone includes a microphone array including a plurality of microphone units, and a two-dimensional filter for filtering an output of the microphone array in the dimensions of both time and space. When the two-dimensional filter is a digital filter and varied in its two-dimensional filter coefficient and sampling frequency, the array microphone serves as a variable directional microphone whose directional characteristic can be varied with the sound quality and level remaining unchanged throughout the recording area.

    摘要： An echo cancellation apparatus cancels an echo signal included in a second speech signal including the echo signal of a first speech signal, and includes: a first echo replica generating unit generating a first echo replica by processing the first speech signal through a filter whose characteristic is equalized with a acoustic transfer function of amplified sound; a first echo cancelling unit generating and providing a first echo-cancelled signal by subtracting from the second speech signal the first echo replica generated by the first echo replica generating unit; and a filter updating unit generating a nonlinear-converted echo-cancelled signal by performing nonlinear conversion on the first echo-cancelled signal generated by the first echo cancelling unit, and updating the filter characteristic thereby equalizing the filter characteristic with the acoustic transfer function, using the nonlinear-converted echo-cancelled signal, the first speech signal, and a norm of the first speech signal.
