Description

This code demonstrates how to configure and use the Xilinx CIC Compiler on LabVIEW FPGA to decimate a sine wave signal.

Additional Information

The compiler is configured with the 100MHz clock, the sigma (input data) sampling frequency is set to 50MHz, and the decimation factor is set to 4. Thus the Nyquist frequency for the input signal will be 12.5MHz/2=6.25MHz. Any input frequency above this will attenuate.
