    Hi Rishinaidusrm (smile)
    please give more details of the signal:
    What is the voltage range of the signal? What is the bandwidth of the signal?

    Measure it on a modern digital oscilloscope. They also typically have the ability to store reference waveforms and you can compare the two. They also usually have the ability to define a band around the reference waveform so that you can define what's acceptable and what isn't -- this is useful for production testing.

    Yes, that is a method, but it's not the only method and scopes are not cheap. Let's see what the signal is all about and try to find a low-cost solution without too much compromise if possible.
