Moku:Lab’s Digital Filter Box

Overview

With Moku:Lab’s Digital Filter Box, you can interactively design and generate different types of infinite impulse response filters with output sampling rates of 122.07 kHz and 15.625 MHz. Select between lowpass, highpass, bandpass, and bandstop filter shapes with up to eight fully configurable types including Butterworth, Chebyshev, and Elliptical.
