Draw a block diagram to show the communication process between a
transmitter and a receiver. By referring to the diagram you draw,
explain the role of ELV systems in enhancing the communication
effectiveness and efficiency.
A tank circuit in a radio transmitter is a series RCL circuit
connected to an antenna. The antenna broadcasts radio signals at
the resonant frequency of the tank circuit. Suppose that a certain
tank circuit in a shortwave radio transmitter has a fixed
capacitance of 1.2 x 10-11 F and a variable inductance. If the
antenna is intended to broadcast radio signals ranging in frequency
from 4.6 MHz to 8.4 MHz, find the (a) minimum and (b) maximum
inductance of...
A radio receiver operating at 477MHz with minimum sensitivity of
-85dBm is connected to an antenna with gain +12dBi using a feeder
cable with loss of -3dB.The transmitter is 40Km away and uses a
parabolic antenna with gain of +23dBi. The transmitter feeds the
antenna through a coaxial cable with -6dB loss. What is the minimum
transmitter power required for reliable operation of the link
assuming a fade margin of 10dB?
1. (10 pts) A mobile receiver communicates with
the transmitter at an operating frequency of 550 MHz at a distance
of 3 km. Calculate the path loss in the system.
2. (15 pts) Assume that two antennas are
half-wave dipoles and each has a gain of 3 dB. If the transmitted
power is 1 W and the two antennas are separated by a distance of 10
km, what is the received power? Assume that the frequency is 100
MHz.
