Problem 4: Voting 2 out of 4 logic is a redundancy scheme utilized in control systems to enhance reliability. It operates by evaluating four input signals and generating a single output based on the majority vote of those inputs. Specifically, the output signal becomes active only when at least two of the input signals are active. Inputs: The voting logic requires four input signals (A, B, C, and D), each originating from distinct sources or sensors. ☐ Output: A solitary output signal (designated as Y) is produced based on the majority vote result of the inputs. Logic Gates: The inputs are connected to a series of AND and OR gates that implement the 2 out of 4 voting logic. Voting: The logic gates are arranged in such a way that the system requires at least two inputs to be in the same state (either high or low) to consider the input valid.

Problem 4:
Voting 2 out of 4 logic is a redundancy scheme utilized in control systems
to enhance reliability. It operates by evaluating four input signals and
generating a single output based on the majority vote of those inputs.
Specifically, the output signal becomes active only when at least two of
the input signals are active.
Inputs: The voting logic requires four input signals (A, B, C, and D),
each originating from distinct sources or sensors.
☐ Output: A solitary output signal (designated as Y) is produced based on
the majority vote result of the inputs.
Logic Gates: The inputs are connected to a series of AND and OR gates
that implement the 2 out of 4 voting logic.
Voting: The logic gates are arranged in such a way that the system
requires at least two inputs to be in the same state (either high or low) to
consider the input valid.
