Hi, I'm into modal analysis. We want to vibrate a body using a combination of sine and random signals. Then we measure the response on a body using accelerometer. The measurement is 1 signal, the need is to separate the signal into two signals (sine and random) and see how close is the measurement to the original signals we used to vibrate the body, thus learning about the nature of interference, accuracy of accelerometers and so on. Does anyone knows how to do it? (not FFT)
Thanks in advance!
