What is defined as "signal noise" in control systems?

Signal noise in control systems refers to unwanted disturbances that interfere with the processing of signals. This noise can be attributed to various sources such as electrical interference, crosstalk between wires, thermal noise from components, or fluctuations in signal sources. In control systems, the integrity of the signal is crucial for accurate processing and control actions; thus, noise can significantly impact the performance and reliability of these systems.

By recognizing that signal noise is detrimental to the clarity and accuracy of the data being processed, engineers and technicians can implement appropriate filtering techniques and signal conditioning methods to minimize its effects. Understanding the nature of signal noise allows professionals to maintain robust and efficient control systems, ensuring that the intended signals can be transmitted and received effectively, free from disturbances that could lead to incorrect interpretations or actions.
