In Figure 2-5, the frequency range is magnified and the Y axis is scaled to cross at
50 Hz for all three cases. Notice that the low speed ADC causes a sensitive attenuation
of the signal when the line frequency is higher than 50 Hz compared to situations when
the line frequency is lower than 50 Hz. The measurement differences can be higher
than 0.2%. To have accurate measurements, without regard for the line frequency, it is
necessary to compensate for these low-pass filter situations.
Errors Caused by Line Frequency.
