1. Briefly outline the reasoning used for the removal of the inconsistency with Maxwell's equations of the intuitively derived fields due to the Hertzian dipole.
2. Discuss the characteristics of the complete electromagnetic field due to the Hertzian dipole.
What functions must the communications stations perform? Repeat for ring and star.
Write the equation that describes the body effect on the transistor - Suggest a modification to the circuit to convert it to a single-ended opamp.
The system must be capable of resolving two aircraft that are separated by 1.00 mile at a distance of 20 miles from the airport. Assuming the receiving dish is circular, what minimum dish diameter is required?
A coil with an unknown resistance and inductance isconnected in series with a resistor of 12 ohms and a capacitor of168 micro farads. The circuit is connected across a 220V 50Hzsupply, with lagging power factor of 0.7145.
The shape of the characteristic curve for a neon lamp is the same as the shape of a characteristic curve for a diode.
A signal is sampled every 1ms for 20ms, with the following actual values of the analogue voltage at successive sampling times. Plot the values of the voltage recorder by a 5 volt, 4 bit ADC assuming that the noise level is much lower
Because the circuit will take a variable amount of time to compute f (it depends on the value of n), an output called done must be provided, which should remain high while the machine is idle. Draw a state transition diagram for a Moore-type machi..
A dc motor is driving a constant-torque load. If the field voltage of the motor decreases by 20%, calculate the percentage change in no load speed.
Write the mathlab program to plot the modulation index necessary to keep the Vdc constant at 1200v when the input power factor angle is varied from -60 degrees to 60 degrees.
