The Fourier series expansion of a real periodic signal with fundamental frequency f 0 is given by $${g_p}\left( t \right) = \sum\limits_{n = - \infty }^\infty {{c_n}{e^{j2\pi {f_0}t}}} ;$$ it is given that c 3 = 3 + j5. Then c 3 is Which one of the following statements is correct? A tunnel diode is always biased Who proposed the idea of transmission of light via dielectric waveguide structure?
