With digital systems, this straightforward physical relationship is lost. Because the dimensions of computer monitors will vary, clear scale markers must be available as part of the display.The operation of EEG amplifiers can also be expressed as gain, denned as the ratio of the output voltage to the input voltage. For example, if an EEG input signal of 10 uV is amplified to 1.0 V in order to move the mechanical pens of an electroencephalograph, then the gain is 1.0/.00001 = 100,000. The gain of an analog or digital system is not as obvious to the user as the sensitivity.
