Description
This IP provides building blocks for creating overlapped FFTs. It leverages LabVIEW FPGA 2014s wide data path FFT to provide support for instruments that process up to 8 samples per cycle.
Included blocks:
Configurable Window
RMS Magnitude
FFT Transpose
FFT Shift
Delayed copies of the FFT are leveraged to create up to 75% FFT overlap. The FFT length is fixed at 1024, but the IP is written such that it can be modified with relative ease to create longer or shorter FFTs.
