.H 1 "Complex FFT"

`CxFft' under `objects' and `dsp processing' converts a complex input
data stream to blocked spectral output. The output of the FFT has
a sample rate just as any other data stream does but the samples
are blocks of complex data. Plot and listing nodes
understand this block structure and display the data accordingly.
`Plot' uses the sample rate and block size to compute a frequency
axis for displaying FFT output.
