suppose that atransmitter sends power into a transmit antenna whose gain is +4bBi. The receiver some distance away receives a powe of -50dBm when operating with a receive antenna whose gain is -3dBi. In order to operate correctly the receiver requires a received power of -40dBm. If we replace the receive antenna with a better onewhat gain in dBi is required of the replacement receive antenna
in a hydroelectric generating station the difference in level between ,the water surface and turbine driving the generators is 425 meters.if 1250 liters of water is required to generate 1 kwh of electric energy.find the overall efficiency
Show that the time displacement in a periodic function has no effect on the magnitude spectrum, but changes the phase spectrum by an amount of -nω0τ radians for the component of the frequency nω0 if the time displacement is τ.
find the complete functions, p(t) and w(t) supplied by the element, not just a number, and graph p(t) and w(t). Choose appropriate intervals of time for your graphs. Assume that both v(t) and i(t) are zero for t
A 50 hp, 460 V, three phase induction motor draws 61 amps when operating at rated voltage and at a power factor of 0.85 lagging when supplying a rated load. knowns: 1hp=746watts effeciency (n) = Pout/Pin = Pout/(Pout+losses)
