Which of the following is not a digital logic function? A) Combinational logic B) Sequential logic C) Parallel logic D) None of the above

Break Down the Problem

1. Identify the types of digital logic functions listed in the options.
2. Determine if "Parallel logic" is recognized as a valid digital logic function.

Relevant Concepts

• Combinational Logic: This refers to circuits where the output is a function of the present input only; examples include adders and multiplexers.
• Sequential Logic: This refers to circuits where the output depends on both the present input and the history of inputs; examples include flip-flops and counters.
• Parallel Logic: This term is less commonly used in the context of defining logic functions. Instead, it may refer to the processing style rather than a logic function itself.

Analysis and Detail

1. Combinational Logic: Valid digital logic function.
2. Sequential Logic: Valid digital logic function.
3. Parallel Logic: Not typically classified under standard digital logic functions.

Verify and Summarize

"Parallel logic" does not generally represent a specific function in digital logic theory. Instead, the term often relates to the way data is processed, not a defined logic function like combinational or sequential.

Final Answer

C) Parallel logic is not a digital logic function.
