FIR Filter Builder

Leverage the versatile Moku FIR Filter Builder to design and implement lowpass, highpass, bandpass, and bandstop finite impulse response (FIR) filters with up to 14,819 coefficients. It’s easy to fine-tune the filter response in the frequency and time domains to complement your specific application. For maximum flexibility, select between four frequency response shapes, five common impulse responses, and up to eight window functions.

It’s easy and convenient to view your signal with the built-in probe points

Use the built-in Oscilloscope to monitor signals throughout the signal path. Need to record critical data? Simply enable the onboard Data Logger and start capturing test results with no extra instruments required.[/lq_image_text_top_bottom]

[lq_image_text_top_bottom image=”14581″]

Visualize your system and configuration in real time

Quickly design filters in the time or frequency domains, choosing from common impulse responses and window functions. Looking to adjust filter parameters? Just tap and drag the corner frequencies.[/lq_image_text_top_bottom]

[lq_image_text_top_bottom image=”14582″]

For total flexibility, select from preset filters or build your own

Choose from impulse response functions like rectangular, sinc, triangular, Gaussian, equation input, or custom, and frequency response functions like lowpass, highness, bandpass, and bandstop filter shapes. Need a Window function? Select from Bartlett, Hann, Hamming, Blackman, Nuttall, Tukey, Kaiser, or none.[/lq_image_text_top_bottom]
