Questions for Experiment $22$

A coupling capacitor ideally looks like a dc:

$($a$)$ open and ac open;

$($b$)$ open and ac short;

$($c$)$ short and ac open;

$($d$)$ short and ac short.

A small Thevenin resistance means the bypass capacitor must be:

$($a$)$ small;

$($b$)$ large;

$($c$)$ unaffected;

$($d$)$ open.

The value of $f_c$ in Table $22-1$ is closest to:

$($a$)100$ Hz ;

$($b$)180$ Hz ;

$($c$)1$ kHz ;

$($d$)5$ kHz $.$

The value of $f_c$ in Table $22-2$ is closest to:

$($a$)100$ Hz ;

$($b$)500$ Hz ;

$($c$)650$ Hz ;

$($d$)1$ kHz $.$

If an $f_c$ of $18$ Hz in Fig. $22-1a$ is needed, the capacitor value must be changed to approximately:

$($a$)0\mathrm{.}1F$;

$($b$)0\mathrm{.}2F$;

$($c$)0\mathrm{.}5F$;

$($d$)1F.$

In Table $22-1,$ the output voltage at $f_c$ is closest to:

$($a$)0\mathrm{.}707$ V ;

$($b$)0\mathrm{.}9$ V ;

$($c$)0\mathrm{.}99$ V ;

$($d$)1$ V $.$

In Table $22-2,$ the output voltage at $f_c$ is closest to:

$($a$)0\mathrm{.}01$ V ;

$($b$)0\mathrm{.}15$ V ;

$($c$)0\mathrm{.}707$ V ;

$($d$)1$ V $.$

When the input voltage is $1$ V in Fig. $22-1$a$,$ the output voltage at $10f_c$ is closest to:

$($a$)0$ ;

$($b$)0\mathrm{.}707$ V ;

$($c$)0\mathrm{.}9$ V ;

$($d$)1$ V $.$
