About this calculator

This calculator computes how much power comes out if a certain input power is subjected to gain or loss, specified in dB or %. Instead of power it is also possible to use pulse energies. The gain or loss is proportional to the input signal and therefore the output is simple some factor times the input.

If gain/loss is given in %, is simply

If gain/loss is given in dB, is

For the example numbers, this evaluates to

So the output power is

And loss in percent is
