Chapter 1, Problem 14E Step-by-step solution Step 1 of 4 Calculate the value of voltage gain, Therefore, the value of voltage gain, is Step 2 of 4 Write the expression for power input of the amplifier. Write the expression for power output of the amplifier. = Since, RL = = Step 3 of 4 Calculate the power gain, Ap. Substitute for and for Ap = = Substitute 10 kΩ for kΩ for and 1 kΩ for Ap = = = 25000 Step 4 of 4 Calculate the value of power gain in decibels. =10(4.39) = 43.9 dB Therefore, the value of power gain, Ap is dB
