Title: David T Crook: Innovator in Synthesizer Technology

Introduction

David T Crook is a prominent inventor based in Summerfield, NC (US). He has made significant contributions to the field of synthesizer technology, holding a total of 9 patents. His work focuses on enhancing the performance and reliability of synthesizers, which are essential in various electronic applications.

Latest Patents

Among his latest patents, Crook has developed innovative synthesizer structures and methods that reduce spurious signals. These synthesizers generate signals in response to primary digital signal representations created by a signal generator. A key feature of his design includes a signal corrector that inserts correction digital signal representations to partially cancel corresponding spurious components in the primary digital signal representation. This results in synthesizer signals with significantly reduced spurious content.

Another notable patent involves feedback methods and systems for rapid switching of oscillator frequencies. This invention allows for quick frequency changes without compromising the operational feedback loop bandwidths that filter out spurious tones and phase noise. The methods respond to frequency changes in a reference signal by providing an open-loop drive current to drive a feedback signal towards the reference signal. The feedback control loop is then closed when the feedback signal is within a predetermined acquisition range of the reference signal.
