Signal amplification performs two important functions: increases the resolution of the input signal, and increases its signal-to-noise ratio.[citation needed] For example, the output of an electronic temperature sensor, which is probably in the millivolts range is probably too low for an analog-to-digital converter (ADC) to process directly.[citation needed] In this case it is necessary to bring the voltage level up to that required by the ADC.
Commonly used amplifiers on signal on conditioning include sample and hold amplifiers, peak detectors, log amplifiers, antilog amplifiers, instrumentation amplifiers and programmable gain amplifiers.[1]
