I am considering there are three signals in my environment but I am interested in getting the signal having frequency 4 KHz.I am adding a Band Pass filter to extract that particular tone and making a delayed copy.Unfortunately I am not getting the output.Check my VI.Suppose if I have unknown signals in the environment and and I want to find out how many of them are are there and what are their frequencies, can we find ?can we visualize independently?

Hello,
We have a lot of examples that appear to perform your desired task. If you are looking to just run a filter on data I would recommend looking at the Filter.vi example found in the NI Example Finer. Help » Find Examples... » Analyzing and Processing Signals » Filtering and Conditioning
For frequency analysis I would recommend looking at the Frequency Analysis of a Filter Design.vi in the Example Finder. Help » Find Examples... » Analyzing and Processing Signals » FFT and Frequency Analysis
If these examples aren't what you are looking for please describe your application and what specific functionality you are looking for.

Filter is not my requirement as I want to make delayed copy of signal and want to visualize it together.I have uploaded a VI in which I am extracting waverform components and in time I am adding delay and construction delayed version.Then I am merging the two signals to visualize together.The whole filter activity I have done is because my sensor is picking two signals and regrdless of proper acquisition, Whatever signal I recieveafter filtering , I am am making delayed copy of it.This is all I want to execute.

Hello,
I apologize for the confusion of what you were looking for. I was able to offset the X-Axis of one set of data using a XY Graph instead of just a Waveform graph. See the attached VI.
