RECORDING AND REPRODUCING DEVICE OF LONG TIME LIVING BODY SIGNAL

摘要

PURPOSE:To improve the time measuring accuracy at reproduction by recording a living body signal and a time signal at the same time and generating a sampling signal synchronously with the time signal at reproduction. CONSTITUTION:The time signal S1 from a generator 1 is recorded on a magnetic tape 3 via a recording device 2. On the order hand, the living body signal S2 is recorded on a track of a tape 3 other than that of the signal S1 by a recording device 4. At reproduction, a PLL1-1 generates a sampling signal synchronously with a time reproducing signal S3. A reproducing device 10 reproduces the recorded living body signal S2 to output a living body reproducing signal S4. The signal S4 is subject to A/D conversion 11 by using the signal S5 and stored in a storage device 13 via a CPU12.
