Abstract:
A fast-operating frequency-shift-controlled system for transmitting information in which a simulated sine wave is generated digitally and in which the frequency of the generated wave is shifted without discontinuities and thereby transmits data at an increased speed.
Abstract:
A fast operating phase-shift-controlled system for transmitting information in which a simulated sine wave is generated digitally and in which the phase of the generated wave is shifted solely at the 0* and 180* points to eliminate ''''ringing'''' and thereby increase the speed at which data may be transmitted.
