Increase the Accuracy of Signal Acquisition via External Interleaved Mode

Digital signal processing is currently the most widespread form of signal processing. The quality of the processed signal depends on the most accurate input data in the form of samples created by AD converters. This article describes the design and use of the External interleaved mode, which can ensure the best possible sampling of input signals and thus increase the accuracy of signal processing several times. The article also compares several options for sensing signals using multiple ADCs and evaluates the quality of the sensed signal. After designing the External interleaved mode, the final device is shown, which includes the functions of measuring true RMS, powers and displaying the frequency spectrum.
