**Transcription for Educational Website:**

The task is to find the trigonometric Fourier series coefficients of the following signal.

**Graph Explanation:**

- **Axes:** The horizontal axis is labeled $ t $ (time), and the vertical axis is labeled $ f(t) $ (signal amplitude).
- **Signal Description:** The function $ f(t) $ appears to have a triangular waveform.
- **Waveform Pattern:**
- Peaks at $ f(t) = 2 $ and troughs at $ f(t) = -2 $.
- The pattern shows symmetry about the vertical axis, implying it's an even function.
- The waveform repeats every 4 units along the $ t $-axis, indicating a period of 4.
- **Key Points:**
- The waveform passes through the origin (0,0).
- Linear segments connect points at $ (-2, 0) $ to $ (0, 2) $, $ (0, 2) $ to $ (2, 0) $, and so on, continuing periodically.

This periodic waveform can be analyzed to determine its Fourier series, which will reveal its frequency components.
