Define a 'Truth Table'
A table that shows the output for every possible input combination
Give disadvantages of having too many logic gates
- Increased complexity of the circuit design
- Increased propagation delay (the amount of time needed for a signal to be received after being sent
- Increased power consumption
What is the name of the sequence Karnaugh maps use and explain how it works
Gray Code sequence. Only one binary bit is changed as you move from one number to the next in the sequence
Give 4 rules of boxes in Karnaugh maps
- They should only contain 1s
- The no of boxes must be 2^n "1s"
-You should aim for the least no of boxes
- boxes can overlap
In floating point binary, the larger the number stored...
The lower its accuracy is
In floating point binary, the smaller the number that can be stored...
The higher its degree of accuracy is
Which direction does the floating point move if the exponent is positive
Right
Which direction does the floating point move if the exponent is negative
Left
Under what condition is a binary number normalised
When it starts with either 01 or 10
