[Songsong Gee]

I am now building a flow graph for ASK modulation,during the test,

Here is my flow graph, http://picasaweb.google.com/lh/photo/-4xnI_UgFeSNENH3UGHgxw?feat=directlink

And this is the result plot, http://picasaweb.google.com/lh/photo/QYy5NJEezHCqaMX-8AIFww?feat=directlink

The bottom is the RX signal. As you can see, RX is not similar with TX, even worse, it is dancing!
