摘要： There is described a method for evaluating a level of noise in a biosignal, the method comprising: receiving a time signal representative of a biological activity, the time signal comprising a biological activity component and a noise component; determining a modulation spectrum for the time signal, the modulation spectrum representing a signal frequency as a function of a modulation frequency; from the modulation spectrum determining a first amount of modulation energy corresponding to the biological activity component and a second amount of modulation energy corresponding to the noise component determining an indication of the level of noise using the first and second amounts of modulation energy; and outputting the indication of the level of noise.
