Abstract:
The invention relates to a method as well as a circuit arrangement for suppression of a perturbing quadrature component of a carrier signal of an amplitude-modulated signal during the recovery of the carrier signal in a synchronous demodulator, which outputs a quadrature signal (Q). The perturbing quadrature component of the carrier signal is estimated and the estimated quadrature component is subtracted from the quadrature signal (Q).
