Abstract

In this project thesis a MATLAB-Tool with a Graphical User Interface (GUI) for independent measuring of impulse responses is implemented.

An impulse response and the corresponding frequency response characterise an existing physical system. It is widely used in parts of acoustics (room- and electro-acoustics) as well as in signal processing and electrical engineering.

Because an ideal impulse is impossible to realise and actual impulses have drawbacks like a low signal-to-noise ratio, two different types of sweeps and a MLS sequence are used as excitation signals.

This tool allows the user to simultaneously measure 8 system responses, from which the corresponding impulse responses are computed and displayed.
