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.
negative logic means negative input values. so by checking the truth table, it becomes an OR gate
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.
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.
A NOT gate is used to invert the input signal, meaning it produces the opposite output to the input. It is commonly used in digital circuits for tasks such as signal inversion, logic gating, and arithmetic operations.
