dude, this is so amazing. Thank you for that. I really loved everything about this. I'm a computer engineer i studied that subject back in a day. You brought back some really good memories. Keep up bro.
Good explanation, I'd say. The capitalisation of systems/signals is something I've learned differently. For me it's capital letters if said function is in the frequency-domain, and lower-case for time domain. So G(s) and g(t). But that might differ from field to field and region to region, as do so many things with notation. Electrical engineering in Germany for me.
@@HerrmannStahl that’s a good point, and that is common convention here in the US too, which gets confusing. If you have x(t), it’s Fourier Transform will be represented as X(f). A system H’s impulse response is often h(t) and its frequency domain representation is H(f). Usually it’s clear on the context if you are reasoning about a system H or its transfer function H(f) or Laplace Transform H(s). In my papers, if I think this becomes confusing, in Latex I’ll use \mathcal{H} to represent the system. But since an LTI system is also characterized by its transfer function, it is common to see H used to refer to the system and its frequency domain representation.
Algorithm randomly suggested this piece of gold. Thank you so much. Subbed.
