How to seperate a superimposed sinusoidal wave from a signal
Could you assist me in isolating a sinusoidal wave that is overlaid(superimposed) on a signal?
I’ve attached a .mat file where a sine wave is superimposed between the 613th and 1569th data points, which have a sampling frequency of 40Hz. My goal is to extract this sine wave from the entire signal. I’ve attempted ‘blind source separation’ techniques, FFT, but it won’t works. the reason might be the frequency of introduced sine wave is too small,only 1Hz.
Additionally, could you provide suggestions on how to identify the point at which a sinusoidal wave is introduced if its location is unknown? Your help would be greatly appreciated.
Thank you in advance!
Comment if any other informantion needed.
