All the inputs of the gate must be set to a logic 1 for the gate to open.
INVERTER gate
inverter gate
When the two input terminals of a NAND gate are short circuited, it acts as a NOT gate.
because some of the logic gate are opened in 0volt
A four input and gate is a logic gate with four inputs. The output is true only when all four inputs are true.
AND gate is an all or nothing gate because in able to have an output of logic 1,all of the input must be all logic 1 or else the output will be nothing or simply logic 0.
the pullup or pull down resistance in the diode logic gate makes it a high output resistance device.If u try to drive another diode logic gate with it the output voltage of the first gate will be affected by the resistance in the second gate.A diode logic gate should always drive a high input resistance input.
negative logic means negative input values. so by checking the truth table, it becomes an OR gate
A NOR gate can be used in various applications, including digital circuits for implementing logic functions such as memory units and arithmetic operations. It is commonly utilized in building complex logic circuits, as it is a universal gate capable of creating any other gate configuration. Additionally, NOR gates are used in control systems, signal processing, and for creating simple multi-input conditions in electronic devices.
A positive logic system will output true only when the input is true. A negative logic system will output true only when the input is false. The NOT logic gate is an example of a negative logic system. That is, NOT( false ) will output true.
because TTL have a bias input setup to eliminate noise therefore the output will follow the logic one input if left open
A positive logic system will output true only when the input is true. A negative logic system will output true only when the input is false. The NOT logic gate is an example of a negative logic system. That is, NOT( false ) will output true.
