I am doing an experiment (I major in physics, not familiar with signal processing so there may be some naive mistakes, please be kind) which requires acting arbitrary pulses on a system.
I use an AWG to generate the pulse (current), bring it to the linear amplifier, and eventually, to a coil (than the current is converted to the magnetic field and act on the system). The pulse will be distorted by the coil and the amplifier, and U want to know the impulse response function (f), so as to modify my input pulse.
Is there a method which can determine the impulse response function experimentally?
I know a little about the method which says: generate a number of input pulses, use an oscilloscope to get the distorted pulse, and f is treated as a matrix which can be determined by multiply the "inverse of input pulse matrix" and the output pulse matrix. Can this really work? Is there a standard method to determine f (I suppose there is)?
