If the dB ratio is positive in value, then it means amplification or gain is present as the output power is greater than the input power (POUT > PIN). An amplifier receives 0 1 W of input signal and delivers 15 W of signal power The power gain in dB
In this video, the Decibel (dB) scale which is commonly used in electronics and communication system is discussed. In this video in this video i have explained why current and voltage gains in decibels are expressed as 20 log of gain and why power gain is The division by 20 is for voltage gain or current gain. For power gain you would use a factor of 10 because power is proportional to voltage or current squared.
