02. If you have a number of radio stations send their own programs at different carrier...
Three radio stations broadcast at three different carrier frequencies: TIL Ulaucasts at three different carrier frequencies: 700 kHz, 1000 kHz, and 1400 Hz The antenna at the radio receiver front-end receives the voltage signals from all three stations, so the input to the radio receiver (tuner) will be the sum of these signals. You are asked to design a parallel resonant RLC circuit with a quality factor of 15 to be used as a tuner to receive only the broadcast...
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...
