1. Fourier series coefficients for Continuous signal # Asking deriving coefficients comes with periodic signal.: \(x(t) \rightarrow a_k\)
1.1 (CT FS) Basic concept of continuous Fourier coefficients # $$ \begin{gathered} x(t): \text { Periodic signal } \ T: \text { Fundamental Period } \ \end{gathered} $$
