Abstract

PURPOSE:To simplify the constitution, by performing the level extension through the use of digital multiplexer. CONSTITUTION:The pulse code and the level control data are inputted to the digital multiplexer 6, the switches S1 to Sn corresponding to each bit of the pulse code signal are switched with the control data, each bit is selected, performing the expanding of the compressed bits. Further, each bit output expanded is reproduced via the D/A converter 7.
