Find $v_3$ such that $\{v_0, v_1, v_2, v_3\}$ is an orthogonal basis of $\mathbb{R}^4$?

Maybe, some day, when the old teachers have all died and modern (differential) geometry finds its way into higher education this answer will be appreciated: $$v_3=\ast\left(v_0 \wedge v_1 \wedge v_2 \...

realistic sampling - where am I wrong?

It is hard to follow what you did as your nomenclature is inconsistent and you didn't explicitly define any of it. I believe the bit you got wrong was the Fourier transform of $h\left[t\right]$, with ...

Fourier series - finding its period from frequency representations

I think that since we’re looking for $\omega_0$ for which $2\pi\sum_n \delta(w -w_0n)$ isn’t 0 at frequencies $|\omega| = 0,3,6,8,9$ we want the delta to have argument 0 at these frequencies. Since $\...

Fourier series - finding its period from frequency representations

HINTS: Note that the given numbers are not indices but actual angular frequencies. So your result should be a number, not just a multiple of the unknown quantity $\omega_0$. In point 2, there's one ...
