WebPositive dB values indicate “gain” while negative ones indicate “loss.” Examples For example, if the gain of an amplifier is A v = −25, then A dB = 20log10 25 = 28dB. We drop the minus sign on the gain because the logarithmic gain doesn’t keep the phase information. If I measure 100mV at the input of a long cable and measure 43mV ...
