Hi Chat, started learning about digital logic systems and voltages are used to represent signals like "0"/ "1" (off/on). How can we send anything more than 0/1? I believe this can be done in 3 ways, not sure which is used practically. 1) Binary (0/1) system paired with multiple signal wires. 2) More voltage levels, total values represented will be #of voltage levels. 3) Single wire sending (0/1) signal with clock, different bit position value at different clock intervals.

clc; clear all;

Oct 23, 2019 12:05
what does this suppose to mean then
Oct 23, 2019 12:05
> compute the sum of all prime digits of a
given number
Oct 23, 2019 11:32
or sum of even digits = 4+4+1+4
Oct 23, 2019 11:32
or sum of even digits = 8+6+5+6
Oct 23, 2019 11:31
then sum of even digits is 8+4+6+6+4
Oct 23, 2019 11:31
when we say find sum of even digits in a large number what does it mean? say number is 84645164
