Susceptibility to Noise: Analog signals are more susceptible to noise and interference, which can degrade signal quality and make it difficult to accurately recover the original information.

Bandwidth Inefficiency: Analog modulation often requires larger bandwidth compared to digital modulation schemes for transmitting the same amount of information.

Limited Data Security: Analog modulation does not inherently provide data security or encryption, making it easier for unauthorized parties to intercept and understand the transmitted information.

Signal Distortion: Analog signals can suffer from distortion due to non-linearities in the transmission medium or equipment, affecting the fidelity of the received signal.

Lower Data Capacity: Analog modulation techniques generally have a lower capacity for transmitting data compared to modern digital modulation schemes, limiting their usefulness for high-speed data transmission applications.
