TRIANGULAR WAVEFORMS IN RC AND RL CIRCUITS.
a. General. Waveforms having gradual rise and decay times are
required in many of the circuits contained in a radar system. A
triangular waveform is shown in Figure 30A. Notice that the waveform
starts at zero and continues to increase at a constant rate (rise
time). When the maximum amplitude has been reached, the waveform
immediately starts decreasing at a constant rate
