Abstract: A measurement method includes generating, by a sensor, a response signal in response to an excitation signal. The method also includes generating a sampling clock signal in accordance with a pseudo-random jitter, and sampling the response signal in accordance with the sampling clock signal to determine a plurality of digital samples. The method also includes combining the plurality of digital samples to form a measurement sample.
