Consider the system shown in Figure 8.23 The signal x(t) is defined by x(t) = A cos
Question:
x(t) = A cos (2Ïfct)
The low pass filter has unity gain in the pass band and bandwidth W, where fc < W. The noise n(t) is white with two-sided power spectral density 1/2 N0 . The signal component of y(t) is defined to be the component at frequency fc. Determine the SNR of y(t).

I have recently received the degree of PhD. In Physics by the Universidade Federal do Maranhão after spending a term in Durham University, as I have been awarded a scholarship from a Brazilian mobility program. During my PhD. I have performed research mainly in Theoretical Physics and published works in distinguished Journals (check my ORCID: https://orcid.org/0000-0002-4324-1184).
During my BSc. I have been awarded a scholarship to study for a year in the University of Evansville, where I have worked in detection-analysis of photon correlations in the the Photonics Laboratory. There I was a tutor in Electromagnetism, Classical Mechanics and Calculus for most of that year (2012).
I am very dedicated, honest and a fast learner, but most of all, I value a job well done.
