Distinguishing signals using neural networks..

hi everyone...

i am a graduate student working on a project which deals with the differentiation among different signals.. i mean distinguishing between them....for this purpose i am trying to use neural networks integrated with back propagation algorithm..
currently i am in a state where i have learnt the algorithm but getting confused in where exactly to start with..

can anyone help me out in this regard?
