#### Figure Description

**Left Diagram: Triangle Waveform Graph**

- The graph illustrates a periodic triangular waveform \( v(t) \).
- The x-axis represents time \( t \), marked in intervals of \( T/2 \), where \( T \) is the period.
- The y-axis represents voltage \( v(t) \).
- The waveform reaches its peak at \( +V_p \) and its trough at \( -V_p \).
- The waveform is symmetric about the vertical axis, with peak points at \( -T/2 \), \( T/2 \), and \( 3T/2 \).

**Right Diagram: Electrical Circuit**

- The circuit diagram shown in Figure P14.29 is a series-parallel RLC circuit.
- **Components**:
  - A 20 Ω resistor.
  - A 40 mH inductor.
  - A 40 nF capacitor.
  - A 180 Ω resistor is connected in parallel to the capacitor.
- **Voltage Inputs and Outputs**:
  - Input voltage \( v_i \) is applied across the series arrangement.
  - Output voltage \( v_o \) is taken across the parallel branch of the capacitor and the 180 Ω resistor.

This circuit can be used to study the behavior of resonant circuits and filter applications. The triangular waveform can be used as an input to analyze the frequency response of the circuit.
