SmartFusion2 SoC FPGA - Adaptive FIR Filter Demo
Adaptive FIR Filter Demo adds the wide band signal (generated inside the Adaptive FIR filter demo
window) to the narrow band signal component and plots the combined signal (Narrowband and
Wideband), FFT spectrum. Refer to the following figure.

4. Click Start to load the input data (1K samples) to the SmartFusion2 device for processing the
filtering operation, refer to the following figure.
Figure 19 • Adaptive FIR Filter Demo - Start
After completing the filter operation, the GUI receives the error data and its FFT data from the Smart-
Fusion2 device and plots as shown in the following figure. The error signal plot shows the
suppression of narrowband component from the wideband signal only after the required number of
iterations.
