Series Circuits(280) A series circuit has a DC voltage source (56 volts), a resistor(72 ohms), a capacitor (82 farads), and a switch. The capacitor is initially uncharged and the switch closes at t=0. Sketch the exponential current and capacitor voltage: i(t)=Aexp(-t/tau) +B, andVc(t)=Dexp(-t/tau) +F.Find: A,B,D,F,tau,i(t=tau),i(t=4tau),Vc(t=tau),and Vc(t=3tau).
A cable TV company delivers video signals over coaxial cable to individual houses. Video signals occupy a bandwidth of 6 MHz and are stacked in frequency from 50 MHz to 656 MHz without guard bands
For the local oscillator you selected, what transmission frequencies could cause interference to the satellite system and how could the interference be avoided? Show a diagram.
What are the two possible frequencies to which the local oscillator could be set? What bandwidth should the 10.7 MHz IF amplifier have?
