FC ATT TEST 5 QUESTIONS AND ANSWERS
FC ATT TEST 5 QUESTIONS AND ANSWERS 1. Transistor amplifiers require what type of signal to function?: DC bias and AC input signals 2. What changes are necessary for amplification to occur?: Small change in base voltage, large change in collector current 3. What amplifier has the best fidelity?: class A 4. What amplifier has the best efficiency?: class C 5. When an input is applied across the emitter to base PN Junction, what is the relative resistance?: low 6. When an input is applied across the collector to base PN Junction, What is the relative resistance?: high, because it is reverse biased 7. The purpose of a transistor is to:: control signals 8.
