\brief A collection of signal analysis functions.
       These are the building blocks for the "signal analyzer" program module
	   of the Gnuradio "RadioMonitor" Application.
	   Many algorithms are inspired by the Octave Time Frequency Toolbox TFTB,
	   but also additional algorithms were collected for this great library.
	   Brief description ends at paragraph border.
	   
A very detailed description here.
Sophisticated mathematical tranformations allow a better insight into radio signals.
This library is an approach to collect all relevant signal analysis functions,
from time frequency distributions over higher order statistical algorithms
to AI signal understanding modules based on neural networks. 
Of course we are only kidding, because this library does not really exist.
This is only a template for heros that want to implement all this.

A small inline formula here \f$(x_1,y_1)\f$, nice in LaTeX.
A display-style formula to describe the mathematical background of this model:
\f[
    |I_2|=\left| \int_{0}^T \psi(t) 
             \left\{ 
                u(a,t)-
                \int_{\gamma(t)}^a 
                \frac{d\theta}{k(\theta,t)}
                \int_{a}^\theta c(\xi)u_t(\xi,t)\,d\xi
             \right\} dt
          \right|

The PDF manual will get a better vector graphics with super fine contours in publishing quality.
