(a) Some antennas have a physical aperture area A that can be identified and is related to the effective area Ae by Ae = ρaA, where ρa is known as the aperture efficiency. For a circular-aperture antenna with a diameter of 2 m and an aperture efficiency of 0.5 at 4 GHz, calculate the power gain.
(b) Referring to Figure, let two such antennas be used for transmitting and receiving, while the two stations are separated by 50 km. Let the total loss over the link be 9 dB, while the transmitter generates 0.5 W. Find the available received power.
Q. Draw the circuit of a two stage RC coupled amplifier?
In terms of negative feedback, there exists an analogy between the operational amplifier and the power-steering mechanism of an automobile. The hydraulic pump is analogous to the p
Q. Explain about Frequency Shift Keying? In this scheme frequency of the carrier signal is changed according to the data. Transmitter sends different frequencies for a "I" than
Classification of Feedback Control Systems by Control Action A more common means of describing industrial and process controllers is by the way in which the error signal E(s) i
Q. Why do we cascade amplifiers? Why is RC coupling the most widely used coupling between 2 stages of a cascading amplifier? The voltage or power gain or frequency response obt
Based on Figure, using star-delta transformation, calculate the current flow and voltage drops at 6kΩ resistor.
A very widely used alternative form of synchronous motor is the ' indu c tion motor'. This has the advantage that it does not require an auxiliary motor to run the rotor up t
The one line diagram of a simple three phase power system is shown in figure below. Each generator is represented by an emf behind the transient reactance. All impedances are expre
