Define logic gate. logic gate synonyms, logic gate pronunciation, logic gate translation, English dictionary definition of logic gate. n. A mechanical, optical, or electronic system that performs a logical operation on an input signal. American Heritage
The simplest gates of all are made from tiny switching devices, called transistors, wired in a certain topology designed to effect the overall gate functionality. Gate里的逻辑一般用diagram来表示。 思考题:Xor(a,b)的canonical representation是如何表示的?它的diagram怎么画? NAND: 可以用NOT + AND进行...
A finite state machine (FSM) can be represented using a state diagram. In computer 45、 science, finite state machines are widely used in modeling of application behavior, design of hardware digital systems, software engineering, compilers, network protocols, and the study of computation and ...
The NAND (Negated AND) gate operates as an AND gate followed by a NOT gate. It acts in the manner of the logical operation "and" followed by negation. The output is false if both inputs are true. Otherwise, the output is true. Another way to visualize it is that a NAND gate inver...
have two-stage circuits in which the circuit inputs are connected to or gates and the circuit output is obtained from an and gate. The minimal sum just defined corresponds to the two-stage circuit in which the output is derived from anorgate and which contains the minimum number of gates....
The circuit diagram above uses NAND gates within the IC. So select switch A to activate the circuit then you can notice that both the LEDs in the circuit will turn off. When the output is low, then the input should be high. After that, select the switch B then both the LEDs will tu...
are shown on the logic diagram of Fig. 2.5.7(b). The truth-table for the NAND gate is shown in Fig. 2.5.7( c). The truth-table for the NAND gate is developed by inverting the output of the AND gate. ‘The unique output from the NAND gate is a LOW only when all inputs are...
Here is a simplified signal diagram and simulation of the circuit. I need to create a truth table for this circuit, but I can't wrap my head around even whether this is a synchronous or asynchronous circuit, because the Clock (well Gate, or Enable, however you want to put it) is conn...

Logic diagram To represent a logic circuit graphically we design logic diagrams. This displays the connection between each individual logic gate with the wiring connection, represented using a specific graphical symbol for each individual logic gate. ...
