The circuit of Figure corresponds to a class B amplifier, where Q1 and Q2 have VBE = 0.7V, VCEsat = 1.2V and RL = 8Ω.
1)Explain why this circuit introduces crossover distortion (crossover) in the output signal.
I think this circuit introduces crossover distortion in the output signal as the two bases of the transistors are directly connected to each other and thus the transistors only starts conducting when Vi> 0.7 V or Vi <-0.7 V, rigth?
2)Determine the average power dissipated in RL when the voltage Vo has the maximum possible extent.(Considering Vi a sine wave with amplitude 9V)
Can i calculate this in this way:
\( Il=(9sqrt(2))^2/8=20,25 W \)
Thanks
