To produce an output waveform that increases at a constant rate,
an integrator circuit may be used with an input voltage that
a.
increases gradually and nonlinearly.
b.
increases gradually and constantly.
c.
increases rapidly and constantly.
d.
remains at a constant value.
17.
Both RC and RL circuits act as differentiators if the circuit
has a specific time constant and if the output is removed from
the correct component. A series RL circuit acts as a
differentiator if the time constant is
a.
short, and the output is taken across R.
b.
short, and the output is taken across L.
c.
long, and the output is taken across R.
d.
long, and the output is taken across L.
18.
What type of circuit and input waveform can be used to obtain a
series of positive and negative triggers?
a.
Lowpass, longtimeconstant circuit with a square wave
input.
b.
Lowpass, longtimeconstant circuit with a triangular wave
input.
c.
Highpass, shorttimeconstant circuit with a square wave
input.
d.
Highpass, shorttimeconstant circuit with a triangular
wave input.
19.
A series RL circuit may be used as an integrator if the output
is taken from across the resistor. This circuit may also be
classified as a
a.
lowpass filter with a longtime constant.
b.
lowpass filter with a shorttime constant.
c.
highpass filter with a longtime constant.
d.
highpass filter with a shorttime constant.
