39 Figure 4C.—Positive clamper. IN ANSWERING QUESTIONS 4-32 AND 4-33, REFER TO FIGURE 4C. 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 3.   Both the resistor and diode 4-33.   How does the length of time required for the capacitor to charge compare to the time for it to discharge? 1.   Charge time is longer than discharge time 2.   Charge time is shorter than discharge time 3.   Charge and discharge times are the same 4-34.   In a positive clamper with positive bias, (a) what extremity of the waveform is clamped and (b) to what potential is it clamped? 1.   (a) Upper (b) positive 2.   (a) Upper (b) negative 3.   (a) Lower (b) positive 4.   (a) Lower (b) negative 4-35.   In a positive clamper with negative bias, (a) what extremity of the waveform is clamped and (b) to what potential is it clamped? 1.   (a) Upper (b) positive 2.   (a) Upper (b) negative 3.   (a) Lower (b) negative 4.   (a) Lower (b) positive Figure 4D.—Clamper with bias. IN ANSWERING QUESTIONS 4-36 AND 4-37, REFER TO FIGURE 4D. 4-36.   With +10 volts of bias in the circuit, what is the maximum negative output voltage? 1.   -15 volts 2.   -25 volts 3.   -40 volts 4.   -50 volts 4-37.   With -15 volts of bias, to what voltage level is the output clamped? 1.   +75 volts 2.   +45 volts 3.   -15 volts 4.   -75 volts
