Title:
デジタル信号処理方法及びデジタル信号処理装置
Document Type and Number:
Japanese Patent JP4162814
Kind Code:
B2
Abstract:
A method of decoding a digital signal includes processing the digital using a delay operation in accordance with a frequency characteristic of 1+D, where D is an output signal of the delay element. The processed digital signal is then converted to a three level conversion signal (0, positive, negative). The conversion signal is then processed in accordance with a frequency of 1/(1+D) to generate a decoded signal. The conversion signal is also checked to determine if there is a conversion error. If a conversion error is detected, propagation of the error is restricted, such that a correct decoded signal is provided.
