Question

A simple AM radio receiver can be constructed as a by the differential equation series RLC circuit which can be modelled da R+ L Vext dt dt where L is the inductance, R is the restance, C is the capacitance, q is the resulting charge point in the circuit, and Vext is the voltage of the signal received in the circuit by an antenna When radio waves pass by the antennae, they create an oscillating voltage (Vext) which induces an alternating current in the circuit. For fixed values of R, L, and C, there is a resonant frequency that maximizes amplitude of the steady state current, and the audio data sent on that signal is what you hear when your radio is on. at a Your company has been hired to of remote forestry sites produce specialty single-frequency AM receivers for a network Your receivers need to maximize the signal amplitude received from base stations, which are broadcasting on the 1,200 kHz frequency Your receivers need to minimize the signal amplitude received from the other commercial radio stations broadcasting across the region, whose signals are in the frequency ranges of 600-1150 Hz and 1220-1600 Hz To design your company's receiver, you have a selection of parts available: One choice of resistor, R = 10 Multiple choices of inductors: - L%3D0.1pH, 0.47рH; 1 р.Н, 4.7рН;B 10рН, 47р/Н; 100р.Н, or 470/H. Multiple choices of capacitors: - C 100pF, 330pF, 680pF, 1nF, 3.3nF, 6.8nF, 10nF, 33NF, 681F, 100nF.

Please explain which components should be used.
