.H 1 "FFT example"

This example adds a complex sine wave to Gaussian noise. This sum
is processed by an FFT. The FFT output and both of the signal
sources are plotted. This example shows how to:

.fi
.AL
.LI
Sum two data streams to generate a single output.
.LI
Link a display node into an existing network.
.LI
Use the Gaussian noise generator.
.LI
Display multiple plots.
.LI
Use he FFT.
.LE
.nf
