- On some digital pink-noise generators the crest factor can be specified.
- Crest factor and PAPR are therefore dimensionless quantities.
- The difference between the peaks and the average for a given signal is the crest factor.
- They decrease the density of clipped samples, and decrease both crest factor and macro-dynamics.
- :: My question concerns the crest factor of OFDM and is a real-world engineering challenge.
- Various crest factors of pink noise can be used in simulations of various levels of dynamic range compression in music signals.
- The measured Crest factor is about 8.3 dB with clipping, and about 10.3 dB without clipping.
- The crest factor of the test signal is a fairly important issue in loudspeaker testing standards; in this context it is usually expressed in dB.
- Such instruments are often calibrated to indicate the RMS value for a sine wave only, but many designs will indicate true RMS within limitations of the wave crest factor.
- Analysis suggests that the loudness trend may have peaked around 2005 and subsequently reduced, with a pronounced increase in overall and minimum album DR ( crest factor ) for albums since 2005.
- For example, the DVB-T signal in 2K mode is composed of 1705 sub-carriers that are each QPSK-modulated, giving a crest factor of 35.32 dB.
- While the crest factor is defined as a positive real number, in commercial products it is also commonly stated as the ratio of two whole numbers, e . g ., 2 : 1.
- In other words, limiters increase both physical and perceptual levels, increase the density of clipped samples, decrease the crest factor and decrease macro-dynamics ( LRA ) given that the amount of limiting is substantial.
- Amplifiers operating with a constant supply voltage become less efficient as the crest factor of the signal increases, because the amplifier spends more time operating below peak power and, therefore, spends more time operating below its maximum efficiency.
- One parameter of noise, the peak versus average energy contents, or crest factor, is important for testing purposes, such as for audio power amplifier and loudspeaker capabilities because the signal power is a direct function of the crest factor.
- One parameter of noise, the peak versus average energy contents, or crest factor, is important for testing purposes, such as for audio power amplifier and loudspeaker capabilities because the signal power is a direct function of the crest factor.
- Deruty and Tardieu analyzed the " loudness range " ( LRA ) over a 45-year span of recordings, and observed that the crest factor of recorded music diminished significantly between 1985 and 2010, but the LRA remained relatively constant.
- :where the trigonometric identity \ sin ^ 2 x = \ frac { 1-\ cos 2x } { 2 } has been used and the factor \ sqrt { 2 } is called the crest factor, which varies for different waveforms.
- Deruty and Damien Tardieu criticized Sreedhar's methods in an AES paper, saying that Sreedhar had confused crest factor ( peak minus RMS ) with dynamics in the musical sense ( " pianissimo " to " fortissimo " ).
- It's puzzling that the ratio between the two numbers is not & radic; 2, but perhaps this is to allow for distorted power waveforms that have higher crest factors than pure sine waves .-- Heron 20 : 47, 4 September 2006 ( UTC)
