Abstract
The present invention relates to digital telephonic system for stethoscope signal processing. Stethoscope sounds are converted to electrical signals and conveyed in digital format to an RS 232 data port (27) of a data transmission product. In the alternate, a modem (26) can be used to convey the signal via a home telephone line. At the receiving end, the reverse process takes place to convert the data back to audible sound. The fidelity and accuracy of the stethoscope sounds is maintained at the receiving end using asynchronous data communications and error protection techniques.
