Recording of physiological signals with domestic videotape storage

Medical & Biological Engineering & Computing, 1991
A system is presented for the recording of physiological signals on an unmodified domestic videocassette recorder (VCR). A modification in the vertical synchronism pulses permits the recording of continuous analogue signals without significant loss of samples. The system allows up to 16 input channels, with a maximum bandwidth of 20 kHz for one channel
