For more information on the Moku Go, Pro and Lab series specifications and applications visit the blog “Are you looking to combine your laboratory into one portable Moku Lab?” or download the datasheets from the download tab.

With Moku’s Digital Filter Box, you can interactively design and generate different types of infinite impulse response filters with output sampling rates of 122 kHz and 15.625 MHz. Select between lowpass, highpass, bandpass and bandstop filter shapes with up to seven fully configurable types including Butterworth, Chebyshev and Elliptical.
