The voltage across a certain load is V =1200*sqrt(2)*30 V, and the load impedance given by Z = 40 j30 ohms . Is the load inductive or capacitive Determine the power factor, complex power, real power, reactive power, and apparent power delivered to the load.
A 300 ohms resistor is connected across the 300 ohms antenna input of a television receiver. The bandwidth of the receiver is 6 MHz, and the resistor is at room temperature (20' C). Find the noise power and noise voltage applied to the receiver in..
Data at a rate of 2 Mbps is to be transmitted via a pass-band communication system whose carrier frequency is 500MHz. A binary antipodal system with roll-off factor of 0.2 is used for this communication. The AWGN single-sided power spectral densit..
You have a 10 nH inductor. What value of capacitor should you put in series with the inductor to achieve an impedance of Z=j50 ohm at f=1.0 GHz
Convert both numbers to 4-bit values, take the 2's complement of 9 and add them. What happens to the carry out How does that compare with what happens when you subtract 8 from 9
The Russian president and the Chinese counterpart need to come to an agreement by telephone. Neither can speak and understand each other's language. They need to employ translators. Compare this layered communication to OSI layers.
The design must show all stages used in its development and must be implemented and tested in PSpice and suitable timing waveforms produced.
What do you believe would happen, if you removed the 220 ohm resistor from the circuit and connected the LED directly to the 555 integrated circuit. Are there any appreciable differences between labeled, calculated.
If you have an M/M/Infinity system with arrival rate lambda and service rate mu(µ), how would you show that the expected number of packets in the queue is equal
First draw the transmit con-stellation and the receive constellation with ideal phase tracking and sampling. Note:they are obviously the same constellations. Now, assume that receiver synchronization is off by a phase angle.
A 3-phase 230 V, 9 kVA, 0.9 PF (lagging) load is supplied by 10 kVA, 1330/230 V, 60 Hz three-phase transformer connected in Y-?. The equivalent impedance of transformer referred to the low-voltage side is 0.12 + j0.25.
A sequential circuit has two inputs w 1 and w 2 , and an output, z. Derive a suitable circuit for the given condition.
A 4800/480 volt, single phase transformer is rated at 75KVA. test results performed for rated power showed the following. short circuit test V=80v, P= 2470W, I= Rated current open circuit test V= 480v, I=4Amp, P=616W
