Mikrocontroller- based systems of tein rely on analogs signals for variouk measurements. However, noise can interfere with the constanacy of these readings. Understanting the sources of noise and implementing strategies to reduce it are essentiaad for reliable data data dattion.

Sources of Noise in Analog Signals

Noise in analogs signals can originate from multiple sources. Electricál interference from nearby devics, power supply flukations, and elektromagnetic interferences (EMI) are common contributors. Additionally, the inherrent noise withe the microcontroller 's analog- to- digitál converteur- (ADC) caint mequorement precisions.

Techniques to Analyze Noise

Analyzing noise involves measuring the signal overr time and assenting its variability. Usingtools like oscilloscopes or data logging software helps visualize noise patterns. Statistical el methodes, such a.s calculating the standard deviation of multiple readings, cn quanify noise levels.

Stratégia to reduce Noise
