27. Calculate the frequency of the 5th harmonic for a square wave with a frequency of 12 kHz. Equation for the square wave is as follows, 4V f(t) = 4 [sin 2x()r + sin 2x(7)r + sin 2x(7)r + ½ sin 2x(7) + ---] — ? 28. Calculate the gain of an amplifier in dB if the input to the amplifier is 20mV and the output to an amplifier is 600mV. 6/7
