Abstract:
A coin validator is arranged to sample the outputs of electromagnetic sensors in order to derive measurements for use in testing coins. Frequency measurements are made by counting a predetermined number of oscillator cycles, terminating the sample period in response to this count being reached, and taking into account the duration of the sampling period and the number of cycles of the oscillator during the sampling period, including any cycles which may have occurred following the predetermined number. The predetermined number is altered in order to change the sampling period.
