A meter driving system receiving pulse signals from a sensor is counting frequencies (Fin) or periods of the input signals. The counted results are weight-averaged to determine an output value (Fn) and a value (Fm) to be indicated. In a weight-averaging process, a weight (α) is varied in response to the frequencies (Fin) of the input signal. Thus, the meter can give a precise indication regardless of varying input frequencies. |
