.SH NAME
.B cascade 
\- Noise and distortion analysis for cascaded systems.

.SH SYNOPSIS
.B cascade
[GNU style options]

.B cascade
file

.SH DESCRIPTION
The
.B cascade
program analyzes the noise and distortion performance of a cascaded
system.  The functional blocks in the system are each characterized
by a gain and optionally noise figure and third order intercept
point.  In addition a source with a particular signal level and
noise level may be specified.
.B Cascade
then calculates the system noise figure and input third order intercept
at each stage.  If the source was specified, the signal level,
carrier to noise ratio, and distortion level is reported at each
stage in the system.

.B Cascade
accepts the following options.
