divide the decimal number by
how do you convert from increments of 2, the binary number
decimal to binary? will be the remainders of the
divisions taken from the bottom up
how do you convert from a divide by 8 and take the remainders
decimal (base 10) to an octal (divide the decimal number by the base you want to convert to)

what does the MSB (most 0: positive
significant bit) of a number 1: negative
represent?


logic gates

MSB = 0: the number is positive
the remaining n-1 bits represent the magnitude

1's Complement MSB = 1: the number is negative
the remaining n-1 bits do not represent the
magnitude to change the sign- invert all the
bits
MSB = 0: the number is positive and the remaining n-1 bits
represent the magnitude

2's Complement MSB = 1, the number is negative, and the remaining n-1 bits
DO NOT represent the magnitude
-to change the sign, invert all the bits and add 1 to the LSB
gray code allows only one bit to change between successive numbers
binary coded decimal
-encoding scheme that encodes using the
BCD code 4 bit binary equivalent

, an open input will float high
in a multiple input AND
-if it does not float high, then the open input will
gate, what happens to an
automatically make the output go low
open input and why?
outputs a 1 when exactly one input is a 1
-inputs must be different to output a
XOR gate high "wink detector"

outputs a high when the inputs
are equal two lows or two highs
XNOR produce a high
