Abstract
Measurement apparatus, for generating a first output signal indicative of a measurand, comprises: a first oscillator circuit and a second oscillator circuit, each oscillator circuit being arranged to generate a respective oscillating output signal and comprising at least a respective first component having a property determining a respective output frequency of the respective oscillating output signal; a sensor for sensing said measurand, the sensor comprising said first component of the first oscillator circuit, said property of said first component of the first oscillator circuit being dependent upon said measurand; and circuitry arranged to receive said oscillating output signals and generate said first output signal, said first output signal being indicative of a number of cycles of one of the first and second oscillating output signals in a time period determined by a period of the other of said first and second oscillating output signals.
