ABSTRACT:
A method and an arrangement for reducing the influence from distortion which is produced when an electrical signal, which is divided into two components, is converted from analogue to digital form. The signal is divided in a phase detector in which it is phase detected with respect to two reference signals, phase shifted 90.degree. with respect to each other. The two components are frequency coded by the reference signals which are provided with a periodic frequency sweep. After the conversion into digital form, each of the components are frequency decoded so that they, with respect to frequency, appear as narrow band signals while possible harmonics which are part of the distortion, are distributed over a frequency range defined by the size of the periodic frequency sweep.
