dB10)x10−3=15.8mWV=√.0158x50Ω=890mVChapter 2, problems 8, 9, 11, 27, and 33 8. State the characteristics of Class A, AB, B and C amplifiers in terms of conduction angle, efficiency, and distortion level.
Class A amplifier conduction angle = 360 degrees Efficiency = 50%, Distortion Level = 0%Class B amplifier conduction angle = 180 degreesEfficiency = 78.5%Distortion Level = -0.7V to +0.7VClass AB amplifier conduction angle = 180 to 360 degrees Efficiency = 50 to 60%Distortion Level = 5 to 10 %Class C amplifier conduction angle = 90 to 180 degrees Efficiency = 100% Distortion Level = high 9. Why are Class C amplifiers unsuitable for use as audio amplifiers?11. How does a frequency multiplier differ from an ordinary RF amplifiers?27. The narrowband RF amplifier in Figure 2.44 has an input signal with a frequency of 12MHz. Calculate:a.The value at which C1should be adjusted for best performance at the signal frequency.
