Consider a transmitter S which radiates a sinusoidal carrier frequency of 1850 MHz. For a vehicle moving at 26.82 m/s, compute the received carrier frequency if the vehicle is moving
(i) Directly towards the transmitter
(ii) Directly away from the transmitter
(iii) In the direction which is perpendicular to the direction of arrival of the transmitted signal
(iv) The transmitted signal is at an angle of 45 degrees to the direction of the vehicle
The constants of an amplifier are given by A = 1, R i =10,000, and R o = 100. It is driven by a Thévenin source with v Th (t) = V O cos ωt and R Th = 20,000 . The amplifier o
