How digital logic gates are built using transistors. Design and build of digital logic systems. Combinational circuits react to the values at their inputs and produce the value of th t t i l t f i bi i f ti f th i i t d t tthe output signal, transforming binary information from the given input data to a required output data The following are the basic steps to design a combinational circuits. y Write down inputs (data, control) and outputs y Draw block diagram or other picture zFormulate the Pro
