### Electrical Circuit Analysis

#### Problem 3(a)

**Circuit Description:**
- A source generates the signal: \( \frac{4}{\pi} \sin 10^3 t \).
- Components in the circuit:
  - Inductor: \(2 \, \text{H}\)
  - Capacitor: \(10^{-6} \, \text{F}\)
  - Resistor: \(3 \, \Omega\)

**Tasks:**
1. **Critical Angular Frequency \( \omega_c = ? \):** Calculate the angular frequency at which the circuit responds most efficiently.
2. **Bandwidth in Angular Frequency \( \Delta \omega = ? \):** Determine the range of frequencies over which the circuit operates effectively.
3. **Transfer Function \( T = ? \):** Find the ratio of the output voltage \( V_o(\omega) \) to the input voltage \( V_i(\omega) \).

#### Problem 3(b)

**Modified Circuit Description:**
- Signal from the source is expressed using the series:
  \[
  \sum_{n=1, \, \text{odd}}^{\infty} \frac{4}{n\pi} \sin(n \times 10^3 t)
  \]
- Circuit components remain the same:
  - Inductor: \(2 \, \text{H}\)
  - Capacitor: \(10^{-6} \, \text{F}\)
  - Resistor: \(3 \, \Omega\)

**Objective:**
- Calculate the output voltage \( V_o \).

#### Note:
The diagrams show an LC circuit (Inductor and Capacitor) in series with a resistor, driven by an AC voltage source. Analyze the circuit to derive expressions for the critical points and functions listed above.
