Abstract
A facsimile receiver includes a demodulator system for converting a received MH code (Modified Huffman Code) signal into a signal representing actual run length information. The demodulator system comprises a demodulation table ROM for comparing the received MH code signal with MH codes stored therein. The leading '0' included in the received MH code signal is counted to provide a portion of an input data to be applied to the demodulation table ROM. When the received MH code signal relates to the terminating code and the input data to the demodulation table ROM becomes identical with one of MH codes stored in the demodulation table ROM, an output data of the demodulation table ROM is utilized without modification to obtain the actual run length information. When the received MH code signal relates to the makup code and the input data to the demodulation table ROM becomes identical with one of the MH codes stored in the demodulation table ROM, six lower bit zero's are added to the output data of the demodulation table ROM to obtain the actual run length information.
