We call it arithmetic or math. Making it plural just sounds weird to an American ear, though it is probably more accurate. Share this post Link to post Share on other sites
kimbuck 746 Posted March 26, 2018 Boolean might not be the correct term,... after all we do lose grey matter with age.. and sometimes life is just plain confusing when standing outside the bathroom doo,r pondering... " have i been or do i need to go? " But i am thinking along the terms of electronics, and IC chips ... "And" gates ...require both inputs to receive a signal to produce an output .. they can combine inputs of energy but if one input stops/fails , the output stops "Nand" gates ( negative and) require both inputs active to turn off the output " Or" gates require an signal at either input ( or both ) to produce an output They can combine signals , as in Ylands energy cases..... they can channel energy from different generators into a single energy stream to power multiple devices " nor" ( negative or gates) require a signal at either or both inputs to turn off the output. There are other ones too, but to bring them into this discussion simply adds complexity and useless information ..which I can excel in This comes from living with someone who builds electronic controllers for a model railroad and leaves burn marks on the carpet and kitchen table from dropped hot soldering irons! But he is a handyman ... he's handy when you need him ( will not elaborate any further....) Share this post Link to post Share on other sites
TheSparkPlug 128 Posted March 26, 2018 Boolean was the correct term One gate which you didn’t want to mention was XOR - it’s a bit like the OR gate, except that only one input can be on - if both inputs are on the output will be off. This is useful for two-way switching... if each switch is fed into the XOR gate, and it’s output sent to a light then either switch can turn the light on/off. 1 Share this post Link to post Share on other sites
kimbuck 746 Posted March 26, 2018 As i said, there were more but i didnt consider discussing them as they are beyond my daily usage requirements! ... hubby spouts off a lot of terms ... inverters, comparators , timers etc etc etc ...i just pour the coffee, nod and nom nom nom on a donut! All electrical components contain smoke ...if you let the smoke escape, they stop working! 1 Share this post Link to post Share on other sites
