Editing Dynamic range (section)

== Electronics ==
In [[electronics]] dynamic range is used in the following contexts: 
* Specifies the ratio of a maximum level of a [[parameter]], such as [[Power (physics)|power]], [[Current (electricity)|current]], [[voltage]]<ref name=slyusar/> or [[frequency]], to the minimum detectable value of that parameter. (See [[Audio system measurements]].)
* In a [[transmission system]], the ratio of the overload level (the maximum [[signal]] power that the system can tolerate without [[distortion]] of the signal) to the [[Noise (electronics)|noise level]] of the system. 
* In [[Digital data|digital]] systems or devices, the ratio of maximum and minimum signal levels required to maintain a specified [[bit error ratio]].
* Optimization of bit width of digital data path (according to the dynamic ranges of signal) can reduce the area, cost, and power consumption of digital circuits and systems while improving their performance. Optimal bit width for a digital data path is the smallest bit width that can satisfy the required signal-to-noise ratio and also avoid overflow.<ref>{{cite journal|doi=10.1109/tcad.2005.859507|title=Dynamic-range estimation|journal=IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems|volume=25|issue=9|pages=1618–1636|year=2006|last1=Bin Wu|last2=Jianwen Zhu|last3=Najm|first3=F.N.|s2cid=11725031|arxiv=0802.3458}}</ref><ref>{{cite book|doi=10.1145/996566.996699|chapter=An analytical approach for dynamic range estimation|title=Proceedings of the 41st annual conference on Design automation - DAC '04|pages=472|year=2004|last1=Wu|first1=Bin|last2=Zhu|first2=Jianwen|last3=Najm|first3=Farid N.|isbn=1581138288|s2cid=8509478}}</ref><ref>{{cite book|doi=10.1109/iccad.2004.1382658|chapter=Dynamic range estimation for nonlinear systems|title=IEEE/ACM International Conference on Computer Aided Design, 2004.

In audio and electronics applications, the ratio involved is often large enough that it is converted to a [[logarithm]] and specified in [[decibel]]s.<ref name=slyusar/>
