Document Type and Number:
Japanese Patent JP3459417
Kind Code:
B2
Abstract:
A method for converting and encoding an analog signal to a digital format and subsequently decoding and converting said digital format to recover the analog signal, comprising the steps of monitoring the physical characteristics of an analog waveform to be converted to a digital format, converting said analog waveform to said digital format, encoding within said digital formal control information indicative of the physical characteristics of said analog waveform, whereby said analog waveform can subsequently be more accurately reconstructed from said digital format, decoding from said digital format said control information indicative of certain specified physical characteristics of said analog waveform, converting said digital format signal to said analog waveform, and peak limiting and restoring, and introducing compatible signal reconstruction compensation, in accordance with said control information during said converting process, said information facilitating subsequent more accurate reconstruction of said analog waveform from said digital format.
