Abstract
A portable data acquisition unit which features a sample order register which sets addresses in a multiplexer unit allowing one out of many electrical signals connected to the multiplexer to pass through at one time. The selected electrical signal is a sample which is transmitted to an A-to-D converter so that a digital signal is generated and passed to a communications port and then to a remote host device. A clock pulse increments the next address in the sample order list to the multiplexer to establish the next signal sample to be transmitted to the host device. At the host device, the original electrical signals may be reconstituted. For example, the electrical signals may be physiological signals derived from transducers associated with an EKG. The host device may be a remote EKG apparatus.
