Improved Phase Modulator-Demodulator.
Abstract
Effort concerns the transferring of digital data over voice communications channels. The contractor (IBM) will develop and construct a digital modulator-demodulator using transistor circuits, phase modulation, and bit synchronism. Progress is presented on the logic design and on the electrical design of each circuit. Progress was satisfactory. Almost all of the circuits were designed and most were tested.
