Is it ok to use MATLAB ''freqs" command for Digital filters?
You should use freqz to calculate frequency response of a digital filter and freqs for an analog filter.
Given a transfer ...

Is it ok to use MATLAB ''freqs" command for Digital filters?
For discrete-time filters, such as FIR and IIR filters, the appropriate Matlab function is freqz.m. You need to evaluate the frequency response on the unit circle of the complex plane; ...

Proper notation for frequency response between $H(\omega)$ and $H(j\omega)$
I'm trying a guess (but that's all it s). To distinguish between complex and real numbers I put a arrow on top of the complex ones.
$\vec{H}(\vec{s}) $ : means $\vec{H}$ is a complex function of a ...

Proper notation for frequency response between $H(\omega)$ and $H(j\omega)$
There's nothing that could be correct or wrong about the notations $H(j\omega)$ and $H(\omega)$, because it's just a matter of convention. The reason why some people use $H(j\omega)$ is that you can ...
