A Band-pass filter showing the centre frequency(Fc), the lower(F1) and upper(F2) cut off frequencies and the bandwidth. The upper and lower cut-off frequencies are defined as the point where the amplitude falls to 3 dB below the peak amplitude. The bandwidth is the distance between the upper and lower cut-off frequencies, and is the range of ...
The peak-to-average power ratio (PAPR) is the peak amplitude squared (giving the peak power) divided by the RMS value squared (giving the average power). [1] It is the square of the crest factor. When expressed in decibels , crest factor and PAPR are equivalent, due to the way decibels are calculated for power ratios vs amplitude ratios .
The {{single chart}} template is available for formatting chart tables for single articles and the {{album chart}} template is for album articles. The use of the templates is strongly encouraged, as they automatically create a correct reference for the chart entry, allow changes to sourcing sites to be accommodated by editing a central location ...
The commonly given measurement of PMPO (peak music power out) is largely meaningless and often used in marketing literature; in the late 1960s there was much controversy over this point and the US Government (FTA) required that RMS figures be quoted for all high fidelity equipment. Music power has been making a comeback in recent years.
A signal at +4 dBu is equivalent to a sine wave signal with a peak amplitude of approximately 1.736 volts, or any general signal at approximately 1.228 V RMS. Peak-to-peak (sometimes abbreviated as p-p ) amplitude (V PP ) refers to the total voltage swing of a signal, which is double the peak amplitude of the signal.
Audio power is the electrical power transferred from an audio amplifier to a loudspeaker, measured in watts.The electrical power delivered to the loudspeaker, together with its efficiency, determines the sound power generated (with the rest of the electrical power being converted to heat).

A potential for ambiguity exists when assigning a level on the dBFS scale to a waveform rather than to a specific amplitude, because some engineers follow the mathematical definition of RMS, which for sinusoidal signals is 3 dB below the peak value, while others choose the reference level so that RMS and peak measurements of a sine wave produce ...
