DIGITAL DATA CODE CONVERSION CIRCUIT FOR VARIABLE WORD-LENGTH DATA CODE

摘要

In a preparation circuit(3) an input variable-word-length code of not more than N0 bits, where N0 equals 16, is divided into codes having word-lengths of not more than N1 bits, where N1 is less than N0 and is eight. Thus for N1 equal to 15, one word of 8 bits and a second word of 7 bits are output. These two words are input to the data code decoder(4). The converter assembles the words input ot it into 8 bit words and outputs them(DO1---DOn1). The data code converter is operated at a rate which is proportional to the data input rate times the number of divisions of the variable-word-length codes.
