Triangular Waveform Plot with Discrete Sampling Points #258142 (License: Personal Use)

This graph displays a periodic triangular wave spanning five complete cycles from x = 0 to x = 200, with amplitude ranging from -1 to +1. Each cycle consists of linearly rising and falling segments, and discrete sample points are marked with open circles connected by vertical stems to the x-axis, indicating a sampled signal representation. The consistent spacing and symmetry suggest idealized digital sampling for analysis or simulation purposes.

Used in educational materials on signal processing, digital communications, or introductory DSP courses; supports explanations of sampling theory, waveform generation, and quantization. Matches user intent for visualizing theoretical waveforms or validating simulation outputs.
