MokuLAb – FIR Filter Builder


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. 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.

Points Clés

• Visualize your signal and configuration in real-time: design filters in the time domain or in the frequency domain • Visualize the filter’s transfer function, impulse and step response, or group and phase delay • Block diagram view of the digital signal processing with built-in probe points for signal monitoring • Load your own filter coefficients or enter an equation to create a customized impulse response
