Overview

With the Moku:Lab 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. The 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.[/lq_Video_image_text_top_bottom]
