What will be the effect if we loading down a tuned-circuit amplifier?(a) it will raise the Q factor of tuned circuit(b) it will lower the Q factor of tuned circuit(c) it will multiply the Q factor by a constant(d) it will have no effect on Q factorI had been asked this question during an internship interview.My enquiry is from Multitone Wideband FM topic in portion Angle Modulation of Analog Communications |
Answer» RIGHT answer is (b) it will LOWER the Q factor of tuned circuit The explanation is: Loading down a tuned circuit will automatically lower the Q factor of any circuit. Q factor characterizes RESONATOR’s BANDWIDTH RELATIVE to its center frequency. It is a measure of the performance of the resonant circuit. |
