Question

You are designing a series RLC circuit to be used in a pocket size AM radio. Keeping the cost and size (surface area) of the circuit to a minimum is the key objective. 4. (25) The table 1 shows the data of the components available to you. Design a series RLC circuit that is critically damped and fulfills the following requirements: It needs to have a resonant frequency of 2.1 M rad/s (within Use a combination of circuit components that minimizes: a. 5%). b. i. Overall cost of the circuit elements used. ii. Minimizes the surface area needed for the circuit elements used. Explain your choices. If the input to the circuit is SV RMS at the resonant frequency, analyze the circuit operation taking into account the ratings of the different components and indicate the power ratings of the components needed in your design. c. d. (Bonus) Table 1.
