Abstract
A signal processing system for a sensor. The system comprises a digital signal processing system configured to set a drive signal frequency for the primary drive transducer, a voltage controlled oscillator configured to receive an input indicative of the resonant frequency and to generate a first periodic signal at a first multiple of the resonant frequency, and a first phase locked loop, configured to receive the first periodic signal, and to generate a second periodic signal at a second multiple of the resonant frequency. The first and second periodic signals are used to control the operation of an analog-to-digital converter (ADC) configured to sample the primary pick off signal and a digital-to-analog converter (DAC) configured to generate a drive signal waveform applied to the primary drive transducer.
