to the guru's, help nman po. paano po ba ma-measure ang total rms power? example sa spec ng speaker, nakalagay ay "15W RMS into 4ohms at 100Hz at 10% THD".. paano ma-measure ung 15W RMS? another is "System THD: Better than 0.05% THD before clipping". paano i-measure ung THD (total harmonic distortion). last e "Signal to Noise Ratio: >80dB". paano i-measure ang SNR?
thanks.
