# Identifying impulse based on experimental data

I have conducted an experiment in which the impulse was exerted on sound bowl (it was hit by a hammer). As a result I have obtained acceleration from accelerometer on 3 axis, calculated net acceleration ($$\sqrt{x^2+y^2+z^2}$$) and tried to obtain frequency components of the response.

What I need to do is to identify input impulse but I have no idea on how to do that.

• what about the input impulse do you need to identify? The way I look at it, you have more unknowns than you have data points: You're observing the convolution of the unknown input impulse with the unknown sound bowl impulse response [convolved with the (hopefully linear) impulse response of your sensor system, but let's assume that's mostly an identity operation]. – Marcus Müller Jan 26 '20 at 10:29
