Abstract :
A system for adaptive sampling of biological waveforms has been developed. A significant feature of the design is that samples are selected at variable rates with the fan algorithm, but transmitted to the user at a fixed permanent rate the user specifies. This approach allows simple computers such as PCs to collect samples at a rate far below the peak sampling rate. Evidence collected with a prototype indicates that accurate measurements of cardiac signals can be obtained at low data rates.<>
