What is the primary function of signal conditioning?

The primary function of signal conditioning is to enhance the quality of a signal for processing. This involves various processes such as filtering, amplifying, converting, and isolating signals so that they can be accurately measured and processed by downstream devices, such as analog-to-digital converters or microcontrollers. Signal conditioning ensures that the signals are within the proper range and format, which is crucial for achieving accurate data representation and reliable performance in a system.

By enhancing the quality of the signal, signal conditioning helps to minimize noise and distortion, thereby allowing better discrimination of the actual signal from any interference. This is particularly important in applications where precision is critical, such as in sensor outputs or communication systems.

While reducing power consumption, increasing circuit load, and amplifying signal strength are important aspects of circuit design, they do not directly encapsulate the broader duty of signal conditioning, which is primarily focused on making signals more suitable for accurate processing and interpretation.
