RC filter is like fizzbuzz for EE.

RC filter is like fizzbuzz for EE.
- rasz 6y agoOne of those is a basic building block used in pretty much everything, the other is software bullshit.
- krapht 6y agoI feel attacked. I'm a DSP engineer and I haven't implemented an analog filter since I graduated. If we got into detail on RC filter gain and phase shift I'd fail. Do I have to give my EE degree back?
- eigenvector 6y agoNo, but you at least realize an analog filter is a thing that exists. You don't remember the specifics, but you could study them if you needed to.
- rasz 6y agoAs an EE you should know what goes in front of ADC to avoid aliasing.
- posterboy 6y agoor you buy a basic building block ADC and follow instructions.
- throwaway348422 6y agoI think it depends on what is meant by details. For a DSP engineer, if details are not knowing the difference between and RC made with ceramic or film cap, I’d give a pass there. If details are not solving continuous time equations in the form 1/s, that’s probably a fail.
- posterboy 6y agoDon't the software methods have very similar problems?
- randomchars 6y agoLooping through a list of items, and doing different operations based on their value is an extremely common occurrence, and you’d hard pressed to find a codebase that doesn’t use that pattern somewhere.
- jmchuster 6y agoWelp, this is why interview fizzbuzz exists, because some people think of it as "software bullshit" instead of the simplest possible program you can imagine that should come out as fast as you can type it.
- posterboy 6y agofizzbuzz is literally a filter, albeit digital, and it involces a circuit, well a loop in most realizations, too. It's probably at the same level of complexity, give or take.
- cushychicken 6y agoAnd, like fizzbuzz, lots of people fail it.
