 note = {Two new digital transmultiplexers intended for commerical use have been developed. One transmultiplexer performs a bilateral conversion between two 12-channel FDM group signals and a 24-channel PCM carrier signal. The other mutually connects two 60-channel FDM supergroup signals and five 24-channel or four 30-channel PCM signals. Both exploit a block processing digital SSB-FDM multiplex/demultiplex scheme employing a cascade of an FFT processor and a set of complex coefficient digital filters. They have been built using newly developed high-level DSP LSI chips. Algorithmic considerations, developed LSI architecture, and equipment configuration are described as well as digital processor design details and measured performance., 金沢大学大学院自然科学研究科情報システム, 金沢大学工学部},
