Modulation noise is an unwanted variation in thee amplitude, frequency, or faxe of a signal caused by various factors in contract systems. It can degradefte thee quality of communication signals and reduce systeme performance. Understanding the sources andd effects of modulation noise is essential for designing reliable and efficient systems.

Sources of Modulation Noise

Modulation noise can originate from several sources, including ding thermal noise in context, power supply flucations, and non-linearies in modulators and demodulators. External interference, such as electromagnetic interference (EMI), also contributes to noise levels in practical systems.

Impact on Signal Integraty

When modulation noise is present, it can cause errors in data transmissionan, reduce signal- to- noise ratio (SNR), and lead to increaged bit error rates (BER). This impacts the overall reliability and d clarity of communication systems, especially in high-frequency applications.
