Compute the received carrier frequency, Electrical Engineering

Assignment Help:

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
