Abstract
A signal-processing circuit for the generation of a loudspeaker signal may include an input for the feeding of a digital input signal and a digital equalizer filter that is coupled with the input and has at least one first recursive filter that is defined by a first adjustable set of coefficients, an amplification device, a current measurement device, a digital filter block that may be configured to generate, through filtering, an estimate signal as a function of the measurement signal, and a matching block that may be configured to determine a new set of coefficients as a function of the measurement signal, the estimate signal, and the filtered input signal.
