Detailed explanation-1: -A simple 2-input logic NOT gate can be constructed using a RTL Resistor-transistor switches as shown below with the input connected directly to the transistor base. The transistor must be saturated “ON” for an inverted output “OFF” at Q.
Detailed explanation-2: -Any number of inputs are possible in OR and AND gates. The AND gate is thus named because it behaves just like the logical “AND” operator. When both inputs are “true, ” the result is “true.” Otherwise, “false” is the output. In other words, only when both inputs, one AND two, are 1 is the output 1.
Detailed explanation-3: -Like the AND gate, the OR function can have any number of individual inputs. However, commercial available OR gates are available in 2, 3, or 4 inputs types. Additional inputs will require gates to be cascaded together for example.
Detailed explanation-4: -Like the AND gate, the OR function can hold any number of individual inputs. However, commercially available OR gates are available in 2, 3, or 4 input types.
