Palette ObjectDescription
DFD Analyze Filter Bank DistortionEvaluates whether a filter bank is a perfect reconstruction filter bank or near-perfect reconstruction filter bank. This VI analyzes the three fundamental distortions in filter banks: aliasing, magnitude distortion, and phase distortion. You also can use this VI to evaluate filter banks that the Filter Bank Design VIs and the DFD Build Filter Bank from Prototype Filter VI create.
DFD Plot Filter Bank Frequency ResponsePlots the frequency responses, including the magnitude and phase responses, for the subband filters of a filter bank.
