Question

Electronics

Good afternoon. Please tell me what knowledge you need to have in order to successfully master radio engineering and related subjects (special sections of the theory of electrical circuits, identification and diagnostics of control systems, circuitry of digital devices, modeling of control systems, theory of automatic control, fundamentals of circuit theory, information networks and telecommunications, technical means of automation and control, electromechanical devices of control systems, microprocessor systems, computers, systems and networks, design of discrete devices, theory and methods of experiment control, devices and details of precision mechanics) at the university?

Answer 1

the main thing is to have experience and practice, your own practice and not institute.
Knowledge is needed only to simplify and rethink practice, to see the rake from afar and not poke like a blind kitten.
Pile something on an arduino, solder a class D sound amp, make a great home lighting. Make an FSK modem on arduino, and then on baremetal. Buy a rover board and make a stepper motor controller for your CNC machine. All this is described from and to and delivers a lot of fun.
And most importantly, although there is almost no demand for electronics engineers and hardware programmers, but if you learn, even in the wilderness, their salaries start from 60-80tr, and in Moscow you can find up to 200tr or take one-time orders is also bold and this is much more interesting than the web which cattle for pay for food.

Answer 2

I also thought, prepared, and so on.
the most important thing is to pass the entrance exams and then not score a bolt.
the rest is nonsense.
