An amplifier is set to a gain of 14.5 dB. If 8.00×10-3 W of electrical power is applied to the input, how much power will be delivered at the output?
-
To convert dB to a factor, divide by 10, raise 10 to this power.
14.5/10 = 1.45
10^1.45 = 28.18
The power has increased by a factror 28.18
8.00×10-3 W x 28.18 = 0.225W
14.5/10 = 1.45
10^1.45 = 28.18
The power has increased by a factror 28.18
8.00×10-3 W x 28.18 = 0.225W
