1.A series RLC circuit has the values R=1 Ohm, C=100pF, L=1.5nH 2.A power amplifier has an output impedance of Zout=100 Ohms. A loud-speaker has an impedance of 8 Ohms. What is the turns ratio of a transformer to match the amplifier to the speaker to maximize the power transfer? 3.Assuming the speed of light is c=3x10^8 meters/second, determine the wavelength of 4.A voice channel has bandwidth from 100 Hz to 10 KHz 5.If a TV station broadcasts 1000 Watts of RF power, and a TV receiver receives 100 microWatts of RF power for that channel, what is propagation path power loss for the TV channel (in dB).
