Q
Design a crossover network to give 12 dB per octave attenuation for critical frequency of 0.5 KHz. Loudspeaker is having resistance of 8 Ω.
AA. C = 200 μf, l = 5.9 mh
BB. C = 28.13 μf, l = 3.6 mh
CC. C = 45.78 μf, l = 2.9 mh
DD. C = 67.34 μf, l = 9.9 mh
Correct Answer:
B. B. C = 28.13 μf, l = 3.6 mh
Explanation:
L = √2RL / 2πfC C = 1 / 2πfC√2RL Substitute the given values in the above equation. C = 1 / 2π × 500 × 1.4 × 8 C = 28.13 μF L = 1.4 × 8 / 2π × 500 L = 11.2 / 1000π L = 3.6 mH
