Daidaitaccen shigarwa

Equivalent input (also input-referred, referred-to-input (RTI), or input-related), is a method of referring to the signal or noise level at the output of a system as if it were due to an input to the same system. This input's value is called the Equivalent input. This is accomplished by removing all signal changes (e.g. amplifier gain, transducer sensitivity, etc.) to get the units to match the input.
