Understanding Electrical Noise: What You Need to Know
Electrical noise, often referred to as electromagnetic interference (EMI) or radio-frequency interference (RFI), is a disturbance that affects electrical circuits, causing undesirable effects on electronic devices. It can originate from various sources and affect the performance of equipment, leading to malfunctions, signal degradation, or data corruption. Sources of Electrical Noise: Electrical noise can arise from internal and external sources: Internal Sources: Generated within electronic devices due to components, such as motors, switches, or microprocessors. External Sources: Stemming from external factors like power lines, motors, transformers, radio waves, or nearby electronic devices. Types of Electrical Noise: Conducted Noise: Occurs through physical conductors, such as power lines or cables. Radiated Noise: Travels through the air in the form of electromagnetic waves, affecting nearby electronic devices. Effects of Electrical Noise: Interference: Disrupts signals betwee...
