Abstract (en)

[origin: EP0967761A1] Following demodulation, characters are assessed using a quality evaluation circuit. The special characteristic curve (16.1) of this circuit includes a hump (17.1) or S-shape. Thus at lower levels of interference, quality is over-estimated; at higher levels quality is under-estimated, in comparison with results from linear circuitry. An Independent claim is included for the corresponding reception circuit.
