Web28 jul. 2024 · you can see a bad signal 0 db noise equal power as signal and a very good signal signal bigger than 40 DB noise. Eb/No = Power signal - Power noise db, so 0 means power noise equal to power of signal, 40 db means power of signal bigger bigger bigger than power of noise . then for you plot calculate the mse, matlab has one … Web17 jul. 2024 · A square wave with amplitude one has a level (power) of 0 dBFs, which means dB Fullscale. Your signal has roughly − 75 dBFs, so that would be a valid result. If you want to get a result in actual physical units, you will need to know several things: the sensitivity of the sensor (e.g. a microphone), that was used for audio recording.
