1 (33). The formula for the frequency of oscillation in an LC circuit is f = 1 2 π LC Here, we must therefore have 88 . 9 × 10 6 = 1 2 π 1 . 4 × 10 - 12 L which gives L = 2 . 2 × 10 - 6 H (35). Again the need the same formula for the frequency. At the top of the band, 1 frequency of 1600kHz means 1 . 3 × 10 6 = 1 2 π 2 × 10 - 6 C which yields C = 7 . 5 × 10 - 9 F and at the bottom . 5 × 10 6 = 1 2 π 2 ×
