Computer Science/Electronics or Electrical/Electronic EngineeringWatch
What you have to understand before choosing a degree is the general areas covered by each of the degrees before picking a degree. A combination degree between two fields usually focusses on the areas in both fields which are close to the interface between those fields. So in a CS+EE degree, you would be exposed to traditional CS courses you wouldn't do on a pure Electronics like compiler design, discrete maths, functional programming e.t.c. In general, room is made for you to take these course by removing some modules that would traditionally be taken in a Electronics degree but are not very close to the interface between CS and EE. So areas not close to the interface like control, semiconductor devices, analogue, RF/Microwave, Optical Communications e.t.c will generally not be available or may be covered only briefly whereas on a pure Electronics degree most of them would be core areas.
Similarly an EEE degree would expose you to Electrical areas like high voltage engineering, power distribution, electrical materials e.t.c but that would mean other areas not very close to the interface that would normally be core courses on an Electronic engineering degree would only be optional courses on an EEE degree and so you will only get to study a subset of them. As Electrical (EL) is very close to Electronics, the set of course available to EEE majors will typically be a superset of both Electrical Engineering and Electronic Engineering modules and so you would have the opportunity to chose optional courses from a much larger pool of courses. For example, where I did my undergrad in the final MEng year of an Electronics degree you would for example have to choose 5 modules from a total of around 40 optional modules whilst on the Electrical degree you would have the choose the same number of modules (5) from around 18 optional modules. On an MEng EEE degree you would have the option of choosing 5 modules from around 48 optional modules.
