PURPOSE:To process organism information easily by sampling the information regarding to the waveforms of organism phenomenon always at a fixed period, digitizing and storing it and then executing the analog reproduction of the waveforms of organism phenomenon on the basis of the stored information. CONSTITUTION:An organism phenomenon signal SG is smapled always at a fixed period, digitized by an A/D converter 12 and stored in a main memory 14 and a submemory 19. Synchronously with the sampling, an analog reproducing signal of organism phenomenon waveforms is obtained from the signal stored in storage means 14, 19 through a multiplexer 24 and a D/A converter 25 and displayed on a CRT8. The contents of the main memory 14 are transferred to the submemory 19 synchronously with the sampling pulse just before the sampling pulse synchronizing with photographing or display. The contents stored in the main memory after sampling by the sampling pulse synchronizing with th photographing and display are immediately transferred to the submemory 19 and, just after the transfer, the contents are immediately photographed or displayed. |
