How can sampling error be minimized
Web10 de jan. de 2024 · As can also be appreciated, the phase plot 930 shown in FIG. 9 is substantially more discrete or discontinuous than the phase plot 1040 shown in FIG. The discrete appearance of the phase plots 930, 1030 is due, for example, to the accuracy of notch filters employed to filter the sensor signal, which can cause coefficient quantization … Web27 de jul. de 2012 · So how can a data-acquisition system reduce quantization errors? Because these errors depend only on an ADCs resolution, sampling at a much higher rate than you would normally spreads the quantization noise over a larger bandwidth. And thus the power density for a fixed bandwidth decreases as f sample increases.
