10. When Diode 2 is shorted by a jumper wire. What will be shown on the oscilloscope display? Remember Diode 2 is near to the PNP transistor which cathode connected to the base of PNP transistor. (1 Point) A sine wave but Positive Cycle with crossover distortion A sine wave but Negative Cycle with crossover distortion Negative cycles with crossover distortion 1.4Vpp 11. What is the conclusion?* (1 Point) Class AB amplifier remove the cross-over distortion signal output Class AB amplifier input signal has lower voltage output than output signal Class AB amplifier without the Input signal, these two transistor NPN and PNP still working Class AB amplifier does have distortion output 12. If the input voltage signal increases, the collector decreases? (1 Point) True False
13. Try to remove either the NPN or PNP transistor in the amplifier circuit. What happens to the output waveform? * If I remove NPN, negative cycle will seen but no positive cycle If I remove both transistors, output is not zero If I remove PNP, negative cycle wil be seen but no positive cycle If I remove NPN, positive cycle will be seen but no negative cycle while PNP will switch ON 14. In Class AB amplifier, the NPN will switch ON if the base is if the base is (1 Point) both are positive cycle both are negative cycle negative cycle, positive cycle positive cycle, negative cycle 15. In Class AB amplifier, if no input signal at the base of two transistors, what is the condition of the two transistors? * (1 Point) NPN is ON while PNP is OFF PNP is OFF while PNP is ON Both are ON Both are OFF
16. What is your observation of the sound output of Class AB amplifier compare to Class B amplifier?* m (1 Point) Class AB and Class B have an equal maximum efficiency Class B has more clearer sound than Class AB amplifier Class AB has more clearer sound than Class B amplifier Class AB and Class B have same quality of sound 17. In class AB amplifier, for the formula Power Output (Po), what you should take Vpp value or Vp value? * (1 Point) O Vpp O vp while D2 connected 18. Diode D1 connected to Vbe of NPN transistor with forward biased of to the Vbe of PNP with forward biased of _____respectively * (1 Point) +0.7V and +0.7V -0.7V and -0.7V 0 -0.7V and +0.7V O 0.7V and -0.7V
