Describe the triangular waveform.
What will be an ideal response?
The triangular waveform consists of positive and negative ramps of equal slope. During the positive alternation the waveform rises at a linear rate from zero to its peak value and then decreases back to zero. During the negative alternation the waveform declines in the negative direction at a linear rate to peak value and then returns to zero. The period of this waveform is measured from peak to peak. Triangular waveforms are used primarily as electronic signals.
