PURPOSE:To enable the reproduction with fidelity having no time delay, by making the analog signal width fed to LPF at reproducing side into less than fractions of the sampling period. CONSTITUTION:The level of the pulse code signal is extended 8 with the pulse signal E obtained with the addition 9 of the level control signal and the control signal D from the transmission side after D/A conversion, and the reproducing output is obtained by feeding the output to LPF 10. At this level extension, the width of analog signal is controlled less than 1/4 of the sampled period at the transmission side. |
