Abstract :
The problem of detecting and estimating the fundamental of an harmonic series in additive noise is often encountered in signal processing. Hinich has proposed a solution: the “harmogram”. We first show the problems encountered with Hinich´s harmogram. Then we propose some solutions to:-avoid the need of knowing the harmonics number;-improve the probability of detection when the fundamental is not a multiple of the inverse of the data number without increasing complexity
