1Transistors are used as amplifying devices. That is, the output sinusoidal signal is greater than the input signal.
- AVerdadero
- BFalso
2According to the conservation of energy, the total power output is not greater than its power input.
- AVerdadero
- BFalso
3The [blank_start]applied DC power[blank_end] is the principal contributor to the total output power even though part of it is dissipated by the device and resistive elements.
- Aapplied DC power
4The peak value of the oscillation in the output circuit is controlled by the established AC circuit.
- AVerdadero
- BFalso
5Which of the following will happen if the designer exceeded the limit set by the DC level?
- AClipping
- BClamping
- CRectification
- DNone of the above
6Which circuit theory is applicable in the analysis and design of the DC and AC components of a BJT network?
- AMillman's Theorem
- BMaximum Load Transfer
- CNorton's Theorem
- DSuperposition Theorem
7A [blank_start]model[blank_end] is a combination of circuit elements, properly chosen, that best approximates the actual behavior of a semiconductor device under specific operating conditions.
- Amodel
8Which of the following models are employed mostly in the formative years of the transistor network? The drawback of this model is it is defined for a set of operating conditions that might not match the actual operating conditions.
- ARe model
- BHybrid model
- CHybrid pi model
9Which of the following model become desirable because of the determination of an important parameter of the equivalent circuit by the actual operating conditions?

- CA reduced version of the re model
- DUsed in low-frequency analysis
- EUsed in high-frequency analysis
- FIncludes the feedback of the output voltage and the input quantities
11The DC levels were simply important because they only determine the DC of the output voltage and not the magnitude of the swing of the AC output.

15The [blank_start]output current[blank_end] is the current through the load resistor Rc.
- Aoutput current
16The AC equivalent of a transistor network is obtained by:
1. Setting all DC sources to [blank_start]zero[blank_end] and replacing them with a [blank_start]short-circuit[blank_end] equivalent.
2. Replacing all capacitors with a [blank_start]short-circuit[blank_end] equivalent.
3. Removing all elements [blank_start]bypassed[blank_end] by the [blank_start]short-circuit[blank_end] equivalents introduced by steps 1 and 2.
4. Redrawing the network in a more convenient and logical form.- Azero
