6 of 20

A swamped amplifier

uses negative feedback

uses positive feedback

is an amplifier whose total emitter resistance is bypassed

is an amplifier that uses base bias

7 of 20

For voltage-divider bias circuits, V CC is

at dc ground

at ac ground

an open to ac current

a high impedance point for ac signals

8 of 20

One way to stabilize the voltage gain of a CE amplifier is to

always use an emitter bypass capacitor

leave some of the emitter resistance unbypassed

use a large load resistance

use a PNP transistor

9 of 20

For a coupling capacitor to work properly, XC should

equal R

be one-tenth or less the series R

be twice the value of the series R

be ten or more times the series R

10 of 20

For dc, a capacitor can be treated like a(n)
