What does the 'decrypting' step do in the demodulation process?

In the context of demodulation, the 'decrypting' step is crucial because it serves to extract the original information from the modulated signal. When data is transmitted over a communication medium, it is often modulated and may also be encrypted for security. The demodulation process involves reversing the modulation to retrieve the signal's original format, while the decryption process specifically allows for the recovery of the original data that had been concealed for protection during transmission.

Choosing the correct option indicates an understanding of how the demodulation process operates in telecommunications and data transmission. Once the signal is demodulated, decryption is necessary for accessing the actual content of the message, as the information could have been transformed through encryption to protect it from unauthorized access. This is an integral part of ensuring that received data remains secure while also making it accessible to authorized users.

The other choices do not accurately describe the purpose of decrypting in this context. Enhancing the signal pertains more to improving quality rather than extracting information. Processing information for clarity may involve additional data handling steps, but it does not specifically relate to the act of decrypting. Converting the signal into digital form refers to a different process that may occur separately from decryption. Hence, the correct interpretation
