The experimental work described here was conducted in an attempt to verify the hypothesis that small variations in the internal anomalies which contribute to errors in digital demodulators cause a lateral displacement of the characteristic curve of bit error rate versus received signal to noise ratio, while the curve retains its theoretical shape at the higher levels of signal to noise ratio. Experiments were conducted on available digital communications systems which encompassed three different methods of modulation. Where feasible, perturbations of error causes were introduced into the systems to determine their effect upon the BER curves.
