EGR 2400 Exam 1
How do you exchange from decimal to binary? - ANS-divide the decimal number through
increments of 2, the binary number will be the remainders of the divisions taken from the bottom
up
how do you change from a decimal (base 10) to an octal quantity? - ANS-divide by eight and
take the remainders
(divide the decimal quantity via the base you need to transform to)
hexadecimal numbers - ANS-0-nine, A, B, C, D, E, F
A= 10
B=eleven
C= 12
D= 13
E= 14
F = 15
what does the MSB (maximum full-size bit) of a number constitute? - ANS-0: fine
1: poor
1's Complement - ANS-MSB = 0: the number is advantageous
the ultimate n-1 bits represent the value
MSB = 1: the number is bad
the ultimate n-1 bits do not represent the magnitude
to exchange the signal- invert all of the bits
2's Complement - ANS-MSB = 0: the range is nice and the ultimate n-1 bits represent the
magnitude
MSB = 1, the wide variety is negative, and the ultimate n-1 bits DO NOT represent the
significance
-to alternate the sign, invert all of the bits and upload 1 to the LSB
gray code - ANS-permits best one bit to change between successive numbers
BCD code - ANS-binary coded decimal
-encoding scheme that encodes the use of the 4 bit binary equivalent
, in a multiple input AND gate, what happens to an open input and why? - ANS-an open input will
glide high
-if it does not go with the flow excessive, then the open input will mechanically make the output
move low
XOR gate - ANS-outputs a 1 whilst exactly one input is a 1
-inputs ought to be one of a kind to output a high
"wink detector"
XNOR - ANS-outputs a excessive whilst the inputs are same
two lows or highs produce a excessive
how can gates be implemented in actual lifestyles? - ANS-switches
what is a transistor? - ANS-basically a miniaturized switch
ex: a TTL chip
DeMorgan's Theorem - ANS-invert all symptoms and transfer -Y 0= -X (low)
1= X (high)
maxterm - ANS-Product of Sums (POS)
ex: M₀, M₁, M₂
zero= X (high)
1= -X (low)
how do you loop for karnaugh maps? - ANS-"single neighbor" pairs
octets
quads
isolated ones
timing diagram with AND gate - ANS-all inputs ought to be excessive for the output to be high
Don't Care Condition - ANS-incompletely certain features
-won't be required to have a definitive 0 or 1 price for some input situations
-input situations never occur in exercise or do now not affect the output cost
-suggest output as "X"
dip switch - ANS-activates (1) and off (zero) sure inputs
what are the two universal gates mentioned in lecture? - ANS-NAND, NOR
can carry out NOT,OR, AND
