I do analog design ( as a hobby, to bad I found out to late electronics is what I like most because otherwise I would like to do it for a living, my knowledge is high enough I think, but no papers)
But i'm confused now, if digital is about 0 or 1, or on/off , is using a comprator making me a digital designer
I think there is no strickt border betweem analog and digital when we talk about the hardware design.
Like working with 74LS logic is kind a digital and routing GHz digital signals is almost analog RF engineering.
It does not matter what the signal is, it are all currents and voltages. I think we must more think of two types of digital designers. The first one is a programmer who is able to connect some basic hardware blocks together. ( like a uP, an LCD, a latch, some external memory, sensors or servo's that can be connected straight to the uP or through a dedicated out of the box " translate/connect" IC.
The other one is basicly an analog engineer but he only works with digital signals, he knows all about bitrates, logic levels, transition times, timing troubles, seperating and filtering signals ect but most of the time he is doing hardware and not programming.
I can transform an analog signal into digital, but when it is digital it stops for me. I can design the microcontroller upin there, interface it, feed it but it will stay braindead because I can not write software. For instance an measure instrument that has a uP in it. I can design the whole thing, but i have to someone my demands for the uP, he then tells me the processor usable, and if it s build i must find someone to write the software.
If I was always using uP's and programming them. i would have designed a program and made hardware needed for the software. I could say I was a digital designer. Maybe ask some advise about the translation from some analog stuff in to digital.
The result of both designers could result in the same instrument. Only the design viewpoint is different.
