Choose The Right FFT Window Function When Evaluating Precision ADCs
When evaluating the dynamic performance of precision ADCs using FFT analysis, coherent sampling provides the best results. In cases where coherent sampling cannot be achieved, a window function with low-side lobes is required to resolve the noise and harmonic components in the frequency spectrum.
Improve Noise Immunity On RTD Ratiometric Measurements
Although external RC filters aren’t necessarily required to achieve an effective ratiometric measurement, adding external filters may prove to be beneficial in applications where the RTD sensor is located remotely in a noisy environment or where sensors are prone to noise pickup.
