    121121The relationship between signal, noise, SNR:
    122 * noise = variance = mean ( signal - mean ( signal ) )
     122* noise = variance = mean ( signal – mean ( signal ) )
    123123* noise [dB] = 10 log (noise power)
    124124* signal [dB] = 10 log (signal power)
    125125* SNR = signal power / noise power
    126 * SNR [dB] = signal [dB] - noise [dB]
     126* SNR [dB] = signal [dB] – noise [dB]
