1. A baseband-controlled passband equalizing arrangement comprising a correction circuit for data signals transmitted by modulating a carrier frequency, a first demodulation circuit cooperating with a carrier recovery circuit for converting these carrier-modulated data signals into base-band signals, and a control circuit acting on variable elements provided in the correction circuit in response to an estimated error of the baseband signals, characterized in that the correction circuit includes at least a recursive part for producing in response to a carrier frequency input signal x(t), which is a continuous function of the time "t", a carrier frequency output signal v(t), which is a continuous function of the time "t" in accordance with the relation : see diagramm : EP0125723,P10,F3 where rl , psi l , rho j , PHI j may be variable elements and there is at least one "l" such that rl #0, and where tau j , tau l are fixed delays and M and N are constants.
