Solution:

A series RLC circuit has R = 20 Ω, C = 0.01 μF, L = 10 mH. Calculate the resonant frequency.

2 kHz

7.4 kHz

15.9 kHz

35.1 kHz

Solution:

The output frequency of a full-wave rectifier is:

Same as the input frequency

Twice the input frequency

Thrice the input frequency

Half the input frequency

Solution:

Negative feedback on a closed-loop control system does not

reduce overall gain

reduce bandwidth

improve disturbance rejection

reduce sensitivity to parameter variation

Solution:

In a MOSFET, the polarity of the inversion layer is the same as the polarity of:

The charge on the gate electrode

The minority carriers in the drain

The majority carriers in the substrate

The majority carriers in the source

Solution:

The electrons and hole concentrations in an intrinsic semiconductor are n_i and p_i respectively. When doped with a p-type material, they change to n and p respectively. Then:

n+p = n_i + p_i

n·p_i = n_i·p

n+n_i = p+p_i

n·p = n_i·p_i

Solution:

In a p-n junction diode under reverse bias, the magnitude of the electric field is maximum at the

edge of the depletion region on the p-side

edge of the depletion region on the n-side

p-n junction

center of the depletion region on the n-side

Solution:

The distinguishing feature between the symbols of a pFET and an nFET switch is

pFET switch has a bubble that denotes it is an active-low switch

pFET switch has a bubble that denotes complement

nFET switch has a bubble that denotes it is an active-low switch

nFET switch has a bubble that denotes complement

Solution:

To prevent distortion in the output signal after amplification, the input signal must be:

Higher than the positive saturation level of the amplifier

Lower than the negative saturation level of the amplifier

Within the negative and the positive saturation level of the amplifier

Both higher than the positive saturation level and lower than the negative saturation level of the amplifier
