Title: Mark D Talbot: Innovator in Frequency Synthesis
Introduction
Mark D Talbot is a notable inventor based in Liberty Lake, WA (US). He has made significant contributions to the field of frequency synthesis, holding 2 patents that showcase his innovative approach to technology. His work primarily focuses on enhancing the capabilities of phase-locked loops and digital frequency synthesizers.
Latest Patents
One of Talbot's latest patents is titled "Frequency modulation in phase-locked loops." This invention describes a phase-locked loop (PLL) frequency synthesizer that incorporates both analog and digital components to provide frequency modulation (FM) of the synthesized output signal. The design features an in-band FM component that is octave scaled and coupled to an analog-to-digital converter, allowing for precise adjustments to the PLL frequency in response to the FM signal. Additionally, the out-of-band FM component is scaled and summed with the PLL error signal to vary the PLL frequency, ensuring a flat frequency response and high signal-to-noise ratio.
Another significant patent by Talbot is the "Multi-channel modulated numerical frequency synthesizer." This invention presents a four-channel multifunction digital frequency synthesizer that utilizes direct numerical synthesis to generate complex output signals. The synthesizer can produce various waveforms, including sine, square, triangle, ramp, and Gaussian noise. It allows for frequency, phase, and amplitude modulation across the channels, enabling a single frequency synthesizer to realize multiple independent channels and support functions within a high-density VLSI integrated circuit.
