    摘要: A method for measuring perceptual quality of voice signals, audio signals, audio-video signals, and multimedia signals in communication equipment in an operational embodiment communicates a processed test signal via a network from a first device to a second device. The processed test signal is then received by an equipment under test, which further processes the processed test signal to recover a representation of the test signal. The recovered test signal is then objectively analyzed to determine a measure of perceptual quality by comparing the recovered test signal to a pre-stored representation of the test signal. A quality measurement unit that conveniently attaches to equipment under test identifies and evaluates quality of recovered test signals communicated from a remote device, or a test signal communicated by the equipment under test. In the latter case, the quality measurement unit communicates with both the equipment under test and with the network, so that the quality measurement unit itself receives a representation of the communicated test signal by the equipment under test.

    摘要: A method for providing real-time perceptual quality measurements of an audio signal (12) in which a quality test signal, including an audio test signal, is received by equipment under test. Playback of a pre-stored representation of the audio signal is coarsely synchronized (20) to the received audio test signal, for example, utilizing a synchronizing pulse in a header of the quality test signal. The playback is then finely synchronized (24) to the received audio signal, for example, by comparing data in a windowed portion of the received audio test signal and a windowed portion of the pre-stored representation of the audio test signal and by adjusting a windowed portion of the pre-stored representation of the audio test signal in accordance with results of the comparison. A window of the received audio test singal is then compared (14) to a portion of the finely synchronized play back of the pre-stored representation of the audio test signal to output a quality measurement of the received audio test signal.

    摘要: A system and method for processing close talking differential microphone array (CTDMA) signals in which incoming microphone signals are transformed from time domain signals to frequency domain signals having separable magnitude and phase information. Processing of the frequency domain signals is performed using the magnitude information, following which phase information is reintroduced using phase information of one of the original frequency domain signals. As a result, high pass filtering effects of conventional differential signal processing of CTDMA signals are substantially avoided.

    摘要: A rotational micro-actuator (20) used in hard disk driver is disclosed. It comprises a frame (21) approximately in the shape of letter “S” and PZT pieces (28, 29) attached to said frame (21), wherein said frame (21) is formed with a central coupling portion (213) by which the micro-actuator (20) is coupled to a suspension tongue (177), and two pieces of said PZT (28, 29) are arranged in central symmetry manner about said central coupling portion (213) such that said micro-actuator (20) can rotate about said central coupling portion (213) in response to the driving signals applied to said PZT pieces (28, 29), thus cause the displacement of the head element secured to the micro-actuator (20) so as to achieve the fine positioning of the head element. With above configuration, the micro-actuator of this invention will not cause the resonance of the suspension base plate during operation. Thereby the servo bandwidth of the hard disk driver is expanded.
