Gain and loss - damping and amplification in dB voltage power conversion - field and energy parameter

The reinforcement and also the amplification factor are called simply "gain" and its increase value with
amplification is positively designated. Loss or decrease is the damping factor,"negative gain" or also"
attenuation". Field and power gain factors and loss factors are ratios.

Conversion

• Field quantities: e. g. Voltage Gain and Loss •
0 dB damping and 0 dB amplification belong to the factor 1
