Error compensator for converting high frequency signals to base band feeds digitized signals of in-phase, quadrature branches to 2-channel adaptive filter, injects test signal during signal pauses
Error compensator for converting high frequency signals to base band feeds digitized signals of in-phase, quadrature branches to 2-channel adaptive filter, injects test signal during signal pauses
The arrangement digitizes the HF signal or a derived IF signal after separation into in-phase and quadrature components. The digitized signals of the in-phase and quadrature branches are fed to a two-channel adaptive filter (20) and a test signal (5) is fed in before signal separation during signal pauses in which there is no signal for conversion.
