Overview

Efficient filterbank based FIR filter

DSP Concepts Proprietary IP.

...

On the Inspector (or Numeric Inspector) you specify the time domain FIR filter coefficients. The module will automatically take care of converting the time domain coefficients into the appropriate frequency domain coefficients. For ease of use, it is better to use the Numeric Inspector and then load the coefficients from a text file.
