crest factor
A method to determine the bandwidth of pulse signals transducers, depending on the crest factor of these signals, is described in this article.
      
An efficient crest factor reduction technique for wideband applications
      
This paper describes a new efficient crest factor reduction technique for wideband applications.
      
The solution involves very little user intervention (which enhances its practical usefulness) and has great benefits compared to multisine signals that minimize crest factor.
      
Afterprecoding the crest factor is significantly reduced and the performance, dueto introduced coding gain, improved.
      
Additionally, low crest factor signals should be preferred in practice due to the limited dynamics of real systems.
      
A low crest factor indicates that most of the elements in the input sequence are distributed near the minimum and maximum values of the sequence.
      
As a guideline, AC sources with a Crest Factor capacity of above 2.5 are adequate to support virtually all end-user equipment.
      
Crest factor is the ratio of peak to RMS signal amplitudes.
      
Crest factor gives essentially the same information as power factor, and is being replaced by power factor in power supply technology.
      
Crest factor greater than 4.3 is guaranteed by design only.
      
Crest Factor is another tool that describes the quality of the output voltage and current for an AC Output.
      
Crest Factor is defined as the ratio of the peak value to the total RMS value.
      
For ground-borne vibration from trains, the crest factor is usually 4 to 5.
      
For all modulated signals, the probe response is a function of the crest factor.
      
For example, the Crest Factor of a pure sine wave is 1.414.
      
It is important when comparing ACPR performance between amplifiers to check the crest factor of the test signal.
      
It is not uncommon for these products to draw non-linear currents with a Crest Factor in excess of 2.5.
      
If the exciting field is pulsed, the crest factor of the signal must be known to correctly compensate for peak power.
      
Information on the crest factor is obtained from the frequency distribution and displayed in the upper right-hand corner of the graph.
