Definition of db gain

WebGain = 1: N = 20 log 10 1 = 0 dB Gain = 0.1: N = 20 log 10 0.1 = -20 dB. The decibel is useful for representing large gains or losses. For example, to say that a voltage signal has increased 100 dB is much easier than to say the signal has increased 100,000 times. The value of using decibels in all cases to describe gain is highly questionable ... WebThe most common absolute dB unit is dBm; it conveys the dB power of a signal with respect to 1 mW. The dBc unit expresses power with respect to the power of a related signal. …
