4. Calculate the amplifier gain using the
following equations:
Gain = (output
amplitude ÷ input amplitude)
= (3.155 V ÷ 130.0 mV) = 24.27
Gain (dB) = 20 x log(24.27) = 27.7 dB

In this example, you want to verify that the
incoming signal to digital equipment meets
its specifications. Specifically, the trans ition
time from a low logic level (0.8 V) to a high
logic level (2.0 V) must be 10 ns or less.
