What component is assessed to have failed if there is no output signal from the system?

When analyzing the situation in which there is no output signal from the system, assessing the transmitter is critical. The transmitter plays a fundamental role in converting input signals (which may be from sensors or other sources) into output signals that can be processed further or delivered to other components in a system. If the transmitter has failed, it would not generate an output signal, leading to the condition described in the question.

Additionally, the transmitter's functionality is essential for the entire communication process within a system. When it operates correctly, it ensures that necessary data is transmitted effectively. A failure in this component can halt operations or lead to incorrect outputs, confirming that an examination of the transmitter is paramount when diagnosing a lack of output signal.

While the power supply, output sensor, and control module are also important components in a system, they serve different functions and may not directly result in the absence of an output signal stemming from a transmitter failure. If the system has power and the control module is functioning properly, the most likely source of a fault that results in no output signal is indeed the transmitter.
