Detailed explanation-1: -Two Input Logic Gates For 2 logical inputs, there are 16 possible logic gates. Table 1 defines the 16 logic gates, shows logical symbol, behavior in symbolic logic, provides name, notes.
Detailed explanation-2: -Detailed Solution. The number of 2-input NAND gates required to implement a 2-input XOR gate is 4.
Detailed explanation-3: -2-input Transistor AND Gate A simple 2-input AND gate can be constructed using RTL Resistor-transistor switches connected together as shown below with the inputs connected directly to the transistor bases. Both transistors must be saturated “ON” for an output at Q.
Detailed explanation-4: -Therefore, the minimum number of 2-input NOR gates needed to implement the function is 3.
