With Moku:Lab’s FIR Filter Builder, you can design and implement lowpass, highpass, bandpass, and bandstop finite impulse response (FIR) filters with up to 14,819 coefficients at a sampling rate of 244.1 kHz. Moku:Lab’s iPad interface allows you to fine-tune your filter’s response in the frequency and time domains to suit your specific application. Select between four frequency response shapes, five common impulse responses, and up to eight window functions.


Visualize your signal and configuration in real-time
Design filters in the time domain or in the frequency domain, choosing from common impulse responses and window functions

Visualize the filter’s transfer function, impulse and step response, or group and phase delay
