Moku:Go’s Digital Filter Box

Overview

With Moku:Go’s Digital Filter Box, you can interactively design and generate different types of infinite impulse response filters with sampling rates of 61 kHz and 3.9 MHz. Select between lowpass, highpass, bandpass, and bandstop filter shapes with up to eight fully configurable types including Butterworth, Chebyshev, and Elliptic.
