Digital techniques__standard Boolean Representations

• we are starting new topic combinational logic circuits. In this topic we are going to learn different combinational circuits like Adder, Subtractor, Mux, DeMux, encoder, decoder etc. 
• combinational circuits generally made of different logic gates. 
• combinational circuits have not any memory or storage space. 
• The output of combinational circuits depends on present input at any instant of time. 
• Here we are discussing standard boolean representations.
