AND Gate. 01.
Scene 4 (20s)
An AND gate is a digital circuit that has two or more inputs and produces an output, which is the logical AND of all those inputs. It is optional to represent the Logical AND with the symbol”.”..
Scene 5 (35s)
TRUTH TABLE. The following table shows the truth table of 2-input AND gate. Here A, B are the inputs and Y is the output of two input AND gate. If both inputs are ‘1’, then only the output, Y is ‘1’. For remaining combinations of inputs, the output, Y is ‘0’. The following figure shows the symbol of an AND gate, which is having two inputs A, B and one output,Y..
Scene 6 (57s)
DIAGRAM OF “AND”GATE. This AND gate produces an output Y, which is the logical AND of two inputs A, B. Similarly, if there are 'n' inputs, then the AND gate produces an output, which is the logical AND of all those inputs. That means, the output of AND gate will be '1', when all the inputs are '1'..
Scene 7 (1m 17s)
OR Gate. 02.
Scene 8 (1m 23s)
An OR gate is a digital circuit that has two or more inputs and produces an output, which is the logical OR of all those inputs. This logical OR is represented with the symbol +’,.
Scene 9 (1m 36s)
TRUTH TABLE. The following table shows the truth table of 2-input OR gate. Here A, B are the inputs and Y is the output of two input OR gate. If both inputs are ‘0’, then only the output, Y is ‘0’. For remaining combinations of inputs, the output, Y is ‘1’. The following figure shows the symbol of an OR gate, which is having two inputs A, B and one output, Y..
Scene 10 (1m 59s)
DIAGRAM OF “OR”GATE. This OR gate produces an output Y, which is the logical OR of two inputs A, B. Similarly, if there are 'n' inputs, then the OR gate produces an output, which is the logical OR of all those inputs. That means, the output of an OR gate will be '1', when at least one of those inputs is '1..
Scene 11 (2m 19s)
NOT Gate. 03.
Scene 12 (2m 25s)
A NOT gate is a digital circuit that has single input and single output. The output of NOT gate is the logical inversion of input. Hence, the NOT gate is also called as inverter..
Scene 13 (2m 39s)
TRUTH TABLE. The following table shows the truth table of NOT gate. Here A and Y are the input and output of NOT gate respectively. If the input, A is ‘0’, then the output, Y is ‘1’. Similarly, if the input, A is ‘1’, then the output, Y is ‘0’, The following figure shows the symbol of NOT gate, which is having one input, A and one output ,Y ..
Scene 14 (3m 0s)
DIAGRAM OF “NOT”GATE. This NOT gate produces an output Y, which is the complement of input, A ..
