    摘要: A digital signal processing device for outputting a holding data in an output register from a DSP in synchronism with a second clock pulse having a frequency lower than that of a first clock pulse for conducting arithmetic processing in the DSP. Accordingly, data to be output from the DSP can be directly read by a microcomputer, and contents in a coefficient memory and a delay time memory, for example, can be updated in accordance with the read data. Further, the digital signal processing device can be applied to an audio apparatus such as a loudness controller and a spectrum indicating apparatus.

    摘要: An audio signal data processing system includes first and second processing devices for processing audio signal data, the first and second processing device having input and output ports of at least two channels, and a control device for controlling the operation of the first and second processing device. The input audio signal data is supplied to the input port of one channel of each of the first and second processing devices, and output data from the output port of said one channel of said first processing device is supplied to the input port of the other channel of the second processing device, and output audio signl data are obtained at each output port of both channels of the second processing device. With this arrangement, one of the cascade processing and the parallel processing can be selectively performed without using a change-over switch provided outside the system.

    摘要: An audio signal data processing system comprises an input device sequentially supplying incoming audio signal data, a data memory control device writing and reading-out the audio signal data into and from a data memory, a delay memory control device sequentially reading-out the audio signal data from the data memory and storing the data into a delay memory and sequentially reading-out the audio signal data from the delay memory and writing the data into the data memory, an arithmetic device multiplying predetermined coefficient data by the audio signal data having been read-out by the delay memory control device and written into the data memory and summing up results of the multiplication. The arithmetic device includes a plurality of multiplication and summing devices multiplying coefficient data by the audio signal data for each of data groups which are obtained by grouping a predetermined number of the audio signal data read-out by the reading device sequentially in the order of reading and subsequently summing up the multiplied values, and a filter device for executing a filter characteristic operation for calculated values respectively obtained by each of the multiplying and summing device, wherein a filter characteristic of the filtering device is made adjustable.

    摘要: A speech synthesizing method which synthesizes speech naturally is disclosed. Standardized frame power values of an n-th frame is calculated when frame power values at head and tail frames in a phoneme are standardized. An average value of the power values sampled from the power frequency characteristics in the n-th frame at a predetermined frequency interval is set as a mean frame power value. A sum of squares of signal levels in one frame of a frequency signal from a sound source is calculated as a frame power correction value. A speech envelope signal is calculated as a function having variables of the standardized frame power values, the frame power correction value and the mean frame power value. The speech envelope signal adjusts the amplitude level of a speech waveform signal supplied from a vocal tract filter according to the level of the speech envelope signal.

    摘要: An electrode forming region for providing lead electrodes (65a, 65b) is provided on a crystal resonator plate (2). Opposed side surfaces (67a, 67b) of a substrate (6) are formed and inclined in the same direction with respect to a front major surface (63). Also, an adhesion reinforcing portion (7) for reinforcing adhesion to a conductive adhesive (5) is provided in the electrode forming region for the lead electrodes (65a, 65b). For example, the adhesion reinforcing portion (7) is a notch portion which is cut and formed in the opposed side surfaces (67a, 67b). Thereby, an adhesion strength of the crystal resonator plate (2) and the conductive adhesive (5) is increased.
