Consider the following problems related to the modulation and power properties of the Fourier transform. (a) The
Question:
(a) The carrier of an AM system is cos(10t), consider the following message signals
i. m(t) = cos(t)
ii. m(t) = r(t) ˆ’ 2r(t ˆ’ 1) + r(t ˆ’ 2), where r(t) = tu(t)
Sketch the modulated signals y(t) = m(t) cos(10t) for these two messages and find their corresponding spectrum.
(b) Find the power Px of a sinc signal x(t) = sin(0.5t)/(Ï€t), i.e., the integral

What I have learnt in my 8 years experience of tutoring is that you really need to have a friendly relationship with your students so they can come to you with their queries without any hesitation. I am quite hardworking and I have strong work ethics. Since I had never been one of those who always top in the class and always get A* no matter what, I can understand the fear of failure and can relate with my students at so many levels. I had always been one of those who had to work really hard to get decent grades. I am forever grateful to some of the amazing teachers that I have had who made learning one, and owing to whom I was able to get some extraordinary grades and get into one of the most prestigious universities of the country. Inspired by those same teachers, I am to be like one of them - who never gives up on her students and always believe in them!
