Question

5. Calculate the resonant frequency for the circuit shown in Figure 14, with the following values: • L = 100 ????µH • C = 0.01 µF • R = 1000 ? (neglect the inductor resistance at this stage). 6. Calculate the Q value (quality factor) for the above circuit, hence the bandwidth, ??. 7. Why do FM stations drop out at shorter distances from their source than AM? 8. What additional components would be required to tune into a digital radio signal rather than a traditional analogue signal? 9. What sort of a noise filter you need to use to suppress the noise from mains electricity in your speakers? Explain.
