The idea for this week's quiz comes from Dick, one of the regular players here on QOTW.

You have a two-tone signal, as is commonly used for amplifier testing, but to make it interesting, this one is a little trickier. The tones are at unequal powers; one is 40 watts and the other is 10 watts. What is

a) the average power of the composite signal?

b) the peak (PEP) power of the composite signal?


50W, 50W

25W, 40W

50W, 90W

50W, 100W


Answer: 50W average, 90W PEP
