Adding & Subtracting Binary numbersview story

http://forum.allaboutcircuits.com – A little confused on this problem... Suppose I have 000111 + 111101 _________ wouldn't I just have 7 - 61 = -68 Thus my answer would be: 1000100 ? But wouldn't I have an overflow? & if i Had an overflow and discarded that 1 then wouldn;t I have the incorrect answer? OR do I need to take the second number and invert it and then add 1?

RPM signal converted to Variable resister question from noobview story

http://forum.allaboutcircuits.com – Hi Ya'll, just found this site looking for a solution to a motorcycle ECU enrichment issue. I have a basic understanding of electronics. The challenge is to take a tachometer signal and tie it to a variable resistance to alter a lambda sensor output to a computer (ECU). I am in the discovery phase, (just starting LOL) and do not know what semiconductor or IC chip or arrangement of electro (Embedded)
