(5) [20 points] Mathematically describe the differences between DSB-AM, USB-AM, and QAM modulators at the transmitter/modulator side; then, interpret those differences of mathematical descriptions in detail based on the physical concept level understanding. What is the motivation and advantage of adopting USB-AM and QAM? Describe in detail for the full credit. (6) [25 points] Mathematically describe the differences between DSB-AM, USB-AM, and QAM demodulators at the receiver/demodulator side; then, interpret those differences of mathematical descriptions in detail based on the physical concept level understanding. If we have DSB-AM modulator and demodulator, launching the USB-AM scheme demands the change of demodula- tion structure at the receiver? What about the case of launching the QAM scheme; it requires change of demodulator structure at the receiver? If the USB-AM and/or QAM requires changes, mathematically describe the changes. What is the motivation and advantage of adopting USB-AM and QAM? Describe as much as you can for the full credit. (7) [15 points] Mathematically describe the Fourier Transform pair of Hilbert transform oper- ation. Prove that Fourier Transform pair. In other words, mathematically derive Inverse Fourier Transform of Hilbert Transform operation in the frequency domain, (-j)sgn(f).
