The resonant or tuner circuit of an AM radio is shown bellow. Given that L=1μH, what must be the range of C to have the resonant frequency adjustable from one end of the AM band to another? The frequency range for AM broadcasting is 540 to 1600 kHz. We consider the low and high ends of the band. Since the resonant circuit is a parallel type, find: a )what is the range of capacitor? b) if you have Qu...
TASK (i): Find time-domain equations for a parallel LC resonant circuit An LC resonant circuit is sometimes referred to as an LC-tank or tuned circuit. It is made up of two components: an inductor (L) and a capacitor (C), hence the name. CAPACITOR 4 e V - + V - Figure 1: Capacitor symbol The charge on a capacitor is proportional to the voltage across it, the constant of proportionality being the capacitance C, measured in Farads (F). Since current...
An electronics hobbyist is building a radio set to receive the AM band, with frequencies from520 kHz to 1500 kHz . The antenna, which also serves as the inductor in an LC circuit, has an inductance of 274 μH . She needs to add a variable capacitor whose capacitance she can adjust to tune the radio. What is the minimum capacitance the capacitor must have? Cmin = ?

We would like to build an AM radio receiver using a series RLC circuit working as a bandpass filter. We have decided to use a 240 μH inductor with an internal resistance of 12Ω, and a variable capacitor whose capacitance varies between 40 to 360 pF. A radio “tunes” into a certain frequency by adjusting its receiver circuit so that it resonates at that frequency, and it only catches that specific frequency. 1. Determine the range of channel frequencies that...
