Abstract
A receiving circuit and method for receiving an amplitude shift keying signal is provided. At least one exponent signal, an exponent-removed in-phase signal, and an exponent-removed quadrature-phase signal are generated from an in-phase input signal and a quadrature-phase input signal. An amplitude is determined as a sum of several summands, whereby the summands are determined from the exponent signal and/or from the exponent-removed in-phase signal and/or from the exponent-removed quadrature-phase signal (Q'), and wherein the amplitude (A) is demodulated.
