Determine the following for the pulse waveforms of Fig. 25.51:
a. whether it is positive-or negative-going
b. base-line voltage
c. pulse width
d. amplitude
e. % tilt
(a)
Whether the waveform is positive going or negative going.
Answer to Problem 1P
The pulse waveform is positive going for case 1 and pulse waveform is positive going for case 2.
Explanation of Solution
Calculation:
Case 1:
Pulse waveform increases in positive direction from the base line therefore it is positive going pulse waveform.
Case 2:
Pulse waveform increases in positive direction from the base line therefore it is positive going pulse waveform.
Conclusion:
Thus, pulse waveform is positive going for case 1 and pulse waveform is positive going for case 2.
(b)
The value of base line voltage.
Answer to Problem 1P
The base line voltage is
Explanation of Solution
