Answer 2

Which of the following is not the sequential logic circuit (d) Subtractor.

Definition of Sequential logic circuit;

Sequential logic circuit- designs the inputs and outputs designs by the rules on the past inputs as well.

Features of Sequential logic circuit;

• Sequential logic circuit depends on clock cycles and past inputs to generate the outputs.
• The memory element is not required as there is no need for feedback.
• It represents the data storage, register, counter, and microprocessor.  
• The subtractor circuits are a part of combinational circuit that performs the subtraction of two binary units.

Therefore, sequential logic circuit represents the counter, register, flip flop circuits to rule the designs.
