The traditional distortion measurement transforms the time signal into the frequency domain to separate fundamental, harmonic and intermodulation components. This technique considers only the mean power in the analyzed interval and neglects the phase information. A new technique for the measurement of the signal distortion in time domain is presented that(More)
A major part of the signal distortion generated by loudspeaker systems are directly related with the geometry and properties of the material used in loudspeaker design and found in all good units passing the assembling line. Those regular distortions are the result of an optimisation process giving the best compromise between perceived sound quality,(More)
A new control technique for electro-dynamical transducer is presented which stabilizes the voice coil position, compensates for nonlinear distortion and generates a desired transfer response by preprocessing the electrical input signal. The control law is derived from transducer modeling using lumped elements and identifies all free parameters of the model(More)
