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.

The Moku FIR Filter Builder is easy to use and offers a range of advanced capabilities to optimize your experiment — at the most cost-effective price in the industry.

Custom test system for comprehensive analysis in FIR Filter

Add a filter stage to your custom test system for comprehensive analysis

Engineered for flexibility, the Moku FIR Filter Builder delivers top performance as a both standalone instrument and a fully integrated component of a custom test sequence in Multi-instrument Mode. Pair it with other software-defined instruments to filter inputs, outputs, or intermediate signals.

Try the software

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.

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.

Impulse/step response statistics in FIR filter

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.

Lock-in amplifier's LabVIEW boxed

Engineered to work seamlessly with your favorite APIs

API integration with MATLAB, LabVIEW, and more allows straightforward automation of your Moku device in complex setups or for repetitive tasks. Save your measurements, screenshots, traces, and other settings locally or to your preferred cloud app. You can also send work to yourself or colleagues within the Moku app.

Engineered for demanding applications

You can’t innovate for the future when your test equipment is stuck in the past. Use the Moku FIR Filter Builder to accelerate development timelines with speed and flexibility unmatched by any other instrument in its class.
