Adders and Flip Flops 4.6
Cards in this deck (9)
- 1Half AdderSince 1+1 results in a double digit number, we need two outputs to the circuit.
The least significant digit is called the sum, and the most significant the carry.
1+1=10
sum = 0 carry = 1 - 2Half Adder
- 3Full AdderFor complex addition (where you may be adding two bytes together), a Full Adder is required
A full adder takes three inputs – the two numbers to be added and a carry bit. This allows full adders to be chained together to add up multiple bits. - 4Full Adder
- 5Full Adder
- 6Full Truth Table
- 7Flip FlopIn digital electronics, a flip flop is a circuit that can be in one of two states (representing 0 and 1), and the state can be changed by an input.It can be thought of as very primitive memory – once it has been put in state 1, it stays there until put in state 0
- 8D Type Flip FlopFlips one bit between 0 and 1. inputs: control input(d) and a clock signal.
Clock signal falling edge = D changes.
Clock signal rising edge = Q
changes. - 9—
