    Function for extracting EMG parameters from time and frequency domains.

    -----------
    Description
    -----------
    EMG signals have specific properties that are different from other biosignals. For example, it is not periodic,
    contrary to ECG signals.
    This type of biosignals are composed of activation and inactivation periods that are different from one another.
    Specifically, there differences in the amplitude domain, in which the activation periods are characterised by an
    increase of amplitude.

    This function allows the extraction of a wide range of features specific of EMG signals.

    ----------
    data : list
        EMG signal.

    sample_rate : int

        If True then it is assumed that the input samples are in a raw format and the output
        results will be in mV.
        When True "device" and "resolution" inputs became mandatory.
