.H 1 "Signal nodes"

The nodes under `objects' and `signal' generate standard
test signal.  They create output data streams as a function
of node parameters. They (along with nodes that read their
input from disk are the initial source of data for a network.

\".LINE Signal generation nodes are shown in Table~\PageRef{Tbl:sig_gen}.
Signal generation nodes include the following:

center;
ll.
Name	Signal type
ConstantData	constant level
Cos	real cosine
CxCos	complex cosine
CxImp	complex impulse or square wave
Normal	Gaussian distributed noise
Ramp	ramp function
UniformNoise	uniformly distributed noise
.TE

You can use the `Add' node (under `objects' and `dsp processing') to sum
2 or more of these signal sources.
