I have pressure data which are measured at a given point in a standing wave. These data(signals) are 'almost' sinusoidal in nature. Each cycle may slightly vary from the original signal i.e the amplitude and frequency of each cycle may be slightly greater or lesser than the (original signal intended by the system) mean signal. How do I calculate this deviation in each cycle? The data set is quiet large-750 Hz signal for 10 seconds. Is there any easier way to do it?
