We can see that $Q$, the linear operator, is analogous to $H$, $v$, the eigenvector, is analogous to $e^{j\omega t}$, and $\lambda$, the eigenvalue, is analogous to $A e^{\jmath \phi}$. | |

I think that following the philosophy of choice on the (academic) correctness over "popularity" of an answer, your answer should be be integrated into the above answer provideded by Lorem Ipsum, which despite being selected as the answer with 96 points by the users, lacks this very important point of view. | |
