\noindent\textbf12. Find Laplace transform of \(t e^-2tu(t)\). \textitAns: \(1/(s+2)^2\), ROC \(\textRe(s)>-2\).
\noindent\textbf14. Use differentiation in Z-domain: \(n a^n u[n] \leftrightarrow \fracaz^-1(1-az^-1)^2\).
\section*Conclusion This document provides a solid foundation in signals and systems problem-solving. Further study should include MATLAB/Python simulations and more advanced topics like state-space representation and filter design.
