Moku:Pro’s Digital Filter Box


With Moku:Pro’s Digital Filter Box, you can interactively design and generate different types of infinite impulse response filters with sampling rates of 305.18 kHz and 39.063 MHz. Select from lowpass, highpass, bandpass, and bandstop filter shapes with up to seven fully-configurable filter types including Butterworth, Chebyshev, and Elliptic. This instrument can be deployed independently or as a part of a Multi-instrument Mode configuration.
