OK, we fgrd out wht sb means, now we nd to no wht CRC stnds 4.
Canadian Royal Croquet?
Canned Roasted Chiles?
Corporation for Regional Curmudgeonry?
Coagulated Roquefort Cheese?
The only CRC I am aware of that even vaguely relates to electtrical engineering is Cyclic Redundancy Checking, as used in serial communications error checking, and I can't see how that would relate to your question.
Nobody is charging you by the word here or limiting you to 146 characters. Please be descriptive so we can help you instead of ridicule you. We love to do that to people who give us an opening, so close that opening by being forthcoming and I for one will forgive and forget and move on.
I can't speak for the others though, some will relish in continuing the good natured ribbing.
