Filter Design Toolbox

Quantized FFTs and Quantized Inverse FFTs

You can specify any type of radix two or radix four quantized FFT in this toolbox with the following data formats:

• Fixed-point FFTs
• Double-precision floating-point FFTs
• Single-precision floating-point FFTs
• Custom floating-point FFTs

The data formats for quantized FFTs are identical to those of quantized filters.
