4-32. When a negative input signal is present,
what components provide(s) the charge
path for the capacitor?
1. Diode only
2. Resistor only

4-33. How does the length of time required for
the capacitor to charge compare to the
time for it to discharge?

time
2. Charge time is shorter than discharge
time
3. Charge and discharge times are the
same
