Title:
DIGITAL AUDIO DISC REPRODUCING DEVICE
Document Type and Number:
Japanese Patent JPS6295769
Kind Code:
A
Abstract:
PURPOSE:To provide an optional transmission characteristic to data by interleaving a sound digital data outputted from a signal processing section at each optional sampling period, reading the result and processing it by a digital signal processor thereby using a simple and low speed processor. CONSTITUTION:A reproduced digital sound signal from a player section 1 is fed to a signal processing section 11, and the sound signal is converted into the 2nd digital signal having the 2nd sampling frequency nfn being n-time of the 1st sampling frequency fn and outputted with the filter characteristic filtering the frequency component below the frequency fs/2 or below. The output of the circuit 11 is fed to digital signal processors 12L, 12R of digital emphasis circuit constitution of the L/R channel digital filter system. The processors 12L, 12R apply scattering processing to the sound signal at each channel. Each output is subject to processing the output data memories 16R, 16L and the result is outputted while being subject to D/A conversion 18.
