FIR Filter Builder overview

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.

Features

Design filters in the time domain or in the frequency domain, choosing from common impulse responses and window functions
Load your own filter coefficients or enter an equation to create a customized impulse response
Visualize the filter's transfer function, impulse and step response, or group and phase delay
Easily save data and upload to the cloud

Specifications

2 independent channels
Up to 15 MS/s sampling rate with 232 coefficients
Over 14,000 coefficients at 244 kS/s
Filter coefficient precision of up to 24 bits
Preset frequency response shapes: Lowpass, Highpass, Bandpass, Bandstop
Window functions: Bartlett, Hanning, Hamming, Blackman, Nuttall, Tukey, Kaiser, or None
AC / DC input coupling
50 Ω / 1 MΩ input impedance

F.A.Q.

Can I load my own filter coefficients?

Yes, you can input your filter coefficients by putting your kernel into a CSV file.

Can I also create IIR filters?

While this instrument (FIR Filter Builder) is used to design FIR filters, you can use the Digital Filter Box to create IIR filters.
