Abstract :
We have developed a new fully-digital adaptive equalizer for teletext receivers which counteracts waveform distortion using teletext signals as reference signals and compensates equalized waveforms. This equalizer reduces the bit error rate vs. video signal S/N to 1/100 that without the equalizer.
