peak signal level การใช้

• With many recordings, high level distortions at signal peaks may be audibly masked by the original signal, thus large amounts of distortion may be acceptable at peak signal levels.
• So, in addition to the main pulse, there are a large number of time sidelobes ( or, more precisely, range sidelobes ) present, the biggest of which are only 13.5 dB below the peak signal level.
• Broadcast engineers in North America usually line up their audio gear to nominal reference level of 0 dB on a VU meter aligned to + 4dBu or-20dBFs, in Europe equating to roughly + 4 dBm or-18 dBFS . Peak signal levels must not exceed the nominal level by more than + 10 dB.
