Question

Given a stationary transmitter is sending at a center frequency of 900 MHz, the receiver is
travelling at speeds of (a) 1 km/hr; (b) 10 km/hr; (c) 100 km/hr; or (d) 500 km/hr. Draw
a graph of four curves that show deviation of spectral frequencies from the center frequency
for the above four scenarios. Use a legend properly to distinguish different scenarios.
