content: Good morning everyone, I'm really stuck on some electronics subjects that I need to study for some exams, but also the issue of understanding more about this area called electronics. One example where I'm "stuck" is in the area of ​​telecommunications (a subject covered in several exams), which I will only have a class related to in the next school term. I managed to get hold of Alcides Tadeu's book "Telecommunications: Transmission and Reception AM-FM", since people spoke very highly of the book, I started trying to learn from it, but unfortunately I didn't understand several points: I understand that the book requires higher mathematics, which I'm currently managing to unravel, but the explanation part is what confuses me the most, because it uses expressions and calculations that sometimes get me lost. I started to study a little about the types of AM modulations (DSB/FC, SSB, etc.) and I understood the demonstrative part, but the formulas (since I'm racing against time for the military exam, I need to learn how to use the formulas soon) are so diverse that it becomes a mess for notes.I'm mentioning telecommunications because it's the biggest obstacle to my own progress at the moment, but it sometimes happens with other subjects. I'd like some advice from someone on what I can try to do.NOTE: I'm talking about Brazil, so the books and references I mentioned are from the country of carnival hahaha, besides that Brazilian video classes often complicate understanding the subject because of the greater level of knowledge required, which is why I rely more on books.

content: Engineering requires university level maths; there is no way around that.And I'm not sure, what your target is - passing a military exam? Is that for getting accepted into the army, hired as an telecommunications engineer or passing university-like exams as an army engineering student?Nevertheless - no maths, no deeper understanding of matters. (When I started to study mechanical engineering, we were asked to take a two-week maths course in advance. My math knowledge was good enough for just one day, then things got crazy. After all, good enough to become a maths teacher later on...)

content: Good luck...Euler was a genius, but I hate himIt requires a lot of study and videos until they "click" on you, there is no fast path, you have to learn them and everyone learns differently.

And I really like mathematics, but in this case, would I need to enter an engineering level to understand something from high school? And the military exam is an example that requires telecommunications (there are other subjects, such as DC and AC circuits, analog electronics, among others).

content: Quote from: Zucca on March 07, 2025, 02:14:36 pmI agree and I am aware that the road to great success is long. I asked here just to see if I could get something to make some tests easier, such as telecommunications (I mentioned it in my post), but I see that the road is hard and I have no problem with that, without effort there is no result!!! Thank you anyway, it is always good to hear the experience of someone in the area.
