I have a signal streaming in from an accelerometer (as shown in the photo below). As you can see, around the 80,000th sample, an event occurs.
I am trying to employ DSP techniques to be able to recognize when this event occurs. I am looking at rolling standard deviation, rolling mean, and setting a threshold to trigger the event notification.
However, I am at these forums to see what your opinions are regarding frequency domain analysis. I am relatively novice at frequency domain engineering, and I was wondering if this event can be recognized by diving into the frequency domain?
Could I do a Short-Time Fourier Transform? FFT?
What are some recommendations on how to recognize when this event occurs?
