Abstract
A system and method are provided for measuring amplifier gain in a digital network. The method includes accepting a digital input signal; amplifying the input signal (Vin); comparing the amplified signal to dc thresholds; measuring output errors; and, calculating the amplifier gain in response to the thresholds. More specifically, accepting a digital input signal includes accepting an input signal having an amplitude. Comparing the amplified signal to dc thresholds includes comparing the amplified signal to a low threshold and a high threshold. Measuring errors includes measuring a predetermined error condition in response to the high threshold and the low threshold. Then, calculating the amplifier gain in response to the thresholds includes calculating the amplifier gain in response to the high threshold, the low threshold, and the input signal amplitude.
