ABSTRACT:
A method of determining Inter-Symbol Interference (ISI) in transmission systems first measures, for each of a plurality of received signal having different Signal-to-Noise (S/N) ratio, the minimum Bit-Error Rate (BER) as a function of the threshold level of a decision circuit at the system receiver. The measurements are then repeated on the system or on a simulated system where one or more segments of the transmission facility has been replaced with one or more non-ISI producing attenuators. The ISI levels for a given BER value is determined from the first and second sets of measurements. An alternate method measures minimum BER values of the system and the simulated system, as a function of the received signal power, for received signals having different S/N ratios. The ISI levels for a given BER value is then determined from these two sets of measurements.
