Abstract
The MODEM WITH DIGITAL ISOLATION removes the relatively large heavy isolation transformer from the Data Access Arrangement and substitutes two tiny pulse transformers between the Integrated Analog and Digital Signal Processor with multiplexers and demultiplexers to eliminate analog distortion and multiple leads, and to accommodate Lap Top/Palm Top computers, while enhancing data speeds. The combination with surge protection enables both uncommon and common mode protection.
