Solution
3.The conduction of Q2 decreases.
Therefore the correct option is A.
4.C1 and R3 are frequency-determining components.
Therefore the correct option is B.
9. 100 countdown is necessary from the divider circuit to produce an output frequency of 10 MHz
Therefore the correct option is B.
11.For a circuit to oscillate, it\'s absolutely essential that the circuit have regenerative feedback.
Since all the circuits dissipate energy. The major problems in oscillators is that the moment they produce oscillations and they also dissipate energy in the passive and reactive elements comprising the “tank / tuned” area, which damps out oscillations. In such conditions, regenerative feedback which feeds on itself helps to sustain oscillations.
Therefore the correct option is B.
12.The circuit is operating normally.
Therefore the correct option is C.
13.The collector-to-emitter junction is open in Q1.
Therefore the correct option is A.
14.Waveform 2
Therefore the correct option is A.
15.Series regulators are inherently more efficient than shunt regulators because the current through the shunt regulator doesn\'t flow through the load.
Therefore the correct option is A.
20.× 3 and × 2
Therefore the correct option is C.
