Abstract
A signal processing system capable of converting various input analog signals including bioelectric signals, such as electrocardiographic signals, electro-encephlographic signals, and pulse wave signals, into digital signals by A/D converter, compressing the converted data by data compression, recording the compressed data on a compressed data recorder, regenerating the compressed data fetched from the compressed data recorder by data regeneration including a Huffman decoder, mode selector and regenerated data forming device, and then providing analog signals corresponding to the regenerated data.
