I would like to get the frequency content (instant frequency or Time-Frequency card) of a signal which is not an audio signal. My signal is a continuous stream of data (200Hz) coming from an accelerometer.

I would like to know what is the highest frequency of my signal.

My first idea is to get a time-frequency card from a matrix I load with my values but th processing and then the time-frequency card will come at the end of my movement. Is it possible to get it at the same time ? (or with little a delay due to the frame size brought by pfft ?)

Motion capture signal frequency content
