Simple Signals

I just wanted to get a simple application programmed up and available for people to see the basics of GNU Radio. In this equivalent of a "hello world," I'm simply creating a couple of signal sources and outputting them to a vector sink. To display the results, I'm using the Python package Matplotlib, which can be easily installed in almost any operating system.

The output is displayed below showing the resulting signal in both time and frequency.

Code: simple.py

sorry to bother you, but, i don't think that i'm getting the images from this site...
the links for the images appear ok.

it could just be my system... thought to ask first.

while this is mainly for radio, could it be used for just audio filtering?

also, is this using haar wavelets?
