Practical Electronics/Tuned Resonance Selected Band-reject

Characteristics

 * $$\frac{V_o}{V_i} = \frac{j\omega L + \frac{1}{j\omega C}}{R + j\omega L + \frac{1}{j\omega C}}$$
 * $$T = RC$$
 * $$\omega_o = \frac{1}{T} = \frac{1}{RC}$$

Characteristics

 * $$\frac{V_o}{V_i} = \frac{j\omega C + \frac{1}{j\omega L}}{R + j\omega C + \frac{1}{j\omega L}}$$

Summary
