Decoder for variable-length codes

摘要

A decoder which decodes variable-length codes by the use of a logical circuit for conversion of the codes the construction of which is simplified. The decoder comprises a shift register which stores an input code therein, the logical circuit which converts the code signal of the shift register into a different code, a detector circuit which detects completion of the code conversion in the logical circuit, and means for inserting a predetermined code into the shift register on the basis of an output of the detector circuit.
