Abstract :
The author presents a new graphical interpretation of Shannon´s famous expression for the tradeoff of the signal to noise ratio E b/N0 and bandwidth efficiency C /W on a bandlimited Gaussian channel. It is shown that the minimum Eb/N0 required to reach the Shannon ideal is the area under the curve tα between t=1 and t=2, where α=C/ W-1. It is pointed out that this interpretation offers tutorial advantages over existing approaches
