Signal distortion measuring and compensating method, e.g. for teletext reception, involves outputting compensated signal as output signal, which has reference signals, whose progression comes next to ideal progression of reference signals

摘要

The method involves compensating an input signal with reference signals (P ref) sequentially at a group delay value of predetermined parameters. Each of the compensated reference signals is compared with an ideal progression of the reference signals. The compensated signal is outputted as an output signal, which comprises the compensated reference signals, whose progression comes next to the ideal progression of the reference signals. An independent claim is also included for a device for measuring and compensating a teletext-signal distortion.
