Abstract
In this paper a procedure for the detection of hidden tones in the spectrum of a signal is proposed and experimentally evaluated. It is based on the IFFTc algorithm ("corrected interpolated FFT") for the estimation of spectral parameters of non-hidden tones, and on the analysis of the disagreement between measured and expected spectra in order to detect hidden tones. The design of the procedure takes advantage of experimental design techniques in the threshold evaluation
