Definition of db gain
WebDefinition of Attenuation in Networking. Attenuation is the loss of signal strength in networking cables or connections. This typically is measured in decibels (dB) or voltage and can occur due to a variety of factors. It may cause signals to become distorted or indiscernible. An example of this is Wi-Fi signal and strength getting noticeably ... 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 ...

The topmost is power gain, … WebThe -3dB point is also known as the "half power" point. In voltage it may not make not make tons of sense as to why we use ( 2 / 2 ), but lets look at an example of what it means in the sense of power. First off, P = V 2 / R, but lets assume R is a constant 1 Ω. Because of the constant 1ohm, we can remove it from the equation all together.
