Improving the detection of evoked responses to periodic stimulation by using bivariate local spectral F-test – Application to EEG during photic stimulation

The spectral F-test has been widely used for automatic detection of periodic signals in noisy environments [1,2], and its definition dates back to seminal works such as those by Rayleigh [3], Schuster [4], Fisher, [5], and Siegel, [6]. Basically, the spectral F-test compares the energy at a given frequency (called signal frequency) with that of the neighbouring frequencies (called noise frequencies). This kind of comparison is often used in clinical practice for detecting, for example, auditory responses in the brain [1,2].
