What is 'Linear to Decibel' conversion function and how to perform it in ASI Datalab?

Linear to dB

This function is used to convert data from Linear (Pascal, g, m/sec etc) to dB. It is mostly used in the field of acoustic but any data can be converted into dB with respect to a reference value. For noise data, dB reference is taken as 20E-6 and for all other, it is taken as 1. It is a logarithmic scale.

Linear to dB conversion is performed using the formula

Output dB = 20 * log10(Input Data Values / Reference)
