Liquid Instruments SW-Pro-FIR Filter Builder

Overview

The SW-Pro-FIR filter builder upgrade for Moku:Pro enables design and implementation of finite impulse response filters with configurable coefficients. Supporting up to 14,819 coefficients at 305.2 kHz or 232 coefficients at up to 39.06 MHz sampling rate, the FIR Filter Builder offers four frequency response shapes, five impulse response options, and eight window functions. Sub-microsecond latency and independent input/output configuration support advanced signal processing applications.
