Title: The Innovations of James C. Hanselman
Introduction
James C. Hanselman is a notable inventor based in San Diego, California. He has made significant contributions to the field of frequency generation technology. His work is characterized by a focus on precision and digital control, which has implications for various applications in electronics.
Latest Patents
Hanselman holds a patent for a "Frequency generator with digitally controlled phase modulation." This innovative frequency generator allows for precise and repeated control of phase modulation through a digital input. The system utilizes a digital-to-analog converter (DAC) to transform digital inputs from a computer into an analog voltage output. An analog ramp signal generator is integrated into the design, enabling the output of both the ramp signal generator and the DAC to serve as inputs to a voltage comparator network. This network switches state whenever the ramp signal exceeds the DAC output, triggering a one-shot multivibrator that produces a square wave. This square wave can be advanced or retarded in phase based on the digital input, ultimately generating a digitally phase-controlled sine wave output.
