Draw the three fundamental components of any communications system. b) What major challenge must these communications systems contend with? Explain 2. We wish to transmit the information signal vm - Ssin (2x6,0001) V. a) Calculate the wavelength of the given signal. b) Would it be practical to directly transmit this information signal using an antenna? Why why not? c) Suppose a carrier signal of ve-10sin (2x250,000t) V is amplitude-modulated by the information signal given above. Sketch and label the frequency spectrum (i.e., the frequency domain representation) of the baseband signal, the carrier signal and the AM signal (three separate sketches are required). d) What is the bandwidth of the AM signal? 3. In the figure shown below, Vis measured as 5.9 V and V measured as 1.2V. 18 In the figure sen below. F…___. it mum V.. (a) Determine the value of (b) Determine the value of V... 5.9 (c) Determine the modulation index. (d) Suppose we can change the value of V. What is the maximum value that we could use for Vm without causing overmodulation?
