The probability distributions of the amplitude of the envelope energy spectrum of both Gaussian noise and amplitude modulated Gaussian noise are derived. From these probability distributions the probability of detection of the modulation is calculated by comparing the distribution at the modulating frequency to the distribution at an adjacent frequency. Confidence percentages as a function of modulation factor are also calculated and compared with experimental results.
