Q3)
(a)
If the SNR of a wireless link is 18dB and the RF bandwidth is 30kHz, using Shannon's
capacity formula, determine the maximum theoretical data rate that can be transmitted.
(b)
Electro Magnetic Interference (EMI) is normally considered either conductive or
radiative. For each type of interference describe at least three ways of reducing their
effects.
If the height of an antenna is 100 metres calculate the difference in metres between
the radio and optical horizons (presume an adjustment factor of 4/3).
If a correctly terminated line has a characteristic impedance of 502 and a measured
velocity of propagation of 2.2 x 108 m/s with an attenuation of 4dB/km. If a fault
develops, and the reflected pulses are returned non-inverted after 10us with a
magnitude 0.05 of that of the transmitted pulse. Calculate the resistance and position
of the fault.
