Unformatted text preview: Use Huffman coding to find the binary codes. What is the average coded message length? Problem 3 • Plot the Fourier Transforms for t f A t c c π 2 cos ) ( = and for t f t f t m m m sin ) ( = ? (You may choose to forfeit the points and ask the TA to give you an answer). • Plot the spectrum of the AM modulated signal t f t Am t u c 2 cos ) ( ) ( = . • What is the energy of the AM modulated signal? • Now suppose we use Phase Modulation with 10 = p k , what is the bandwidth of the PM signal? • Now suppose we use Frequency Modulation with 10 = f k , what is the bandwidth of the FM signal? • Describe how you would obtain SSBSC from ) ( t u , and plot the corresponding spectrum. • We use a BPF given as follows to filter ) ( t u to give ) ( t v . Plot the spectrum of the resulting signal....
