hello. lets say i have 2 signals, signal A and signal B. signal A was acquired in a quiet ie noise-free environment, signal B was acquired in a noisy environment. is there a way i can use the information from signal A ie the ground truth, to remove the noise from signal B? what techniques are currently available for doing so? thanks, Russell

You're describing the "Wiener filter". https://en.wikipedia.org/wiki/Wiener_filter. If you have the Image Processing Toolbox, use wiener2().
