What is 'Decibel to Linear' conversion function and how to perform it in ASI Datalab?
dB to Linear
This function is used to convert data from decibel to linear. Decibel is mostly used in the field of acoustic but any dB data can be converted into linear with its reference. For noise data, dB reference is taken as 20E-6 and for all others, it is taken as 1. It is a logarithmic scale.
Decibel to linear conversion module requires signal unit as input which is used for selecting the reference. The calculation is done using the formula
Output Linear = Reference * 10(dB/ 20)
