Final answer:
The correct answer is 'c' diagnostic, as the blank values from a vehicle's computer that represent electrical operating values are typically handled as digital signals in modern vehicle systems.
Step-by-step explanation:
The blank values produced by a vehicle's computer give electrical operating values of sensors, actuators, and circuits. These values are known as diagnostic outputs, as they are used for troubleshooting and ensuring that everything in the vehicle is functioning correctly. The question appears to be related to the nature of these outputs, whether they are analog or digital. Given the context of modern vehicles, which often contain complex computer systems, the signals are typically in digital form. This is because digital signals, which consist of binary code, are more suitable for the electronic processing that takes place within the vehicle's computer systems.
In addition, in modern electronic devices, including vehicle computers, transistors function as on-off switches in digital circuits, handling digital signals with fixed voltage values. Integrated circuits with transistors are crucial in digital signal processing. Hence, the correct answer to the student's question is option 'c', diagnostic outputs, which in vehicles are typically handled as digital signals.
