Question

The carrier frequency generated by a tank circuit containing 1 nF capacitor and 10 $\mu$ H inductor is

• A. 1592 Hz
• B. 159.2 MHz
• C. 159.2 kHz
• D. 159.2 Hz

Answer 1

The correct option is C 159.2 kHz

v = $\frac{1}{2\pi \sqrt{LC}}=\frac{1}{2\times 3.14\sqrt{10\times {10}^{-6}\times 1\times {10}^{-9}}}$ = 159.2 KHz
