Which of the following is NOT a step in the demodulation process?

The demodulation process involves several steps that transform a modulated carrier wave back into its original data form. Each of these steps works to retrieve the signal content that was altered during modulation.

Receiving the modulated carrier wave is the first vital step, as it's essential to have the signal present for demodulation to occur. Filtering is also a critical step in the process; it helps remove unwanted frequencies or noise, ensuring that the output signal is as clear and accurate as possible. Lastly, decrypting the information is necessary when the data has been encrypted before the modulation process, as it enables the extraction of the original data from the received signal.

In this context, amplifying the signal is not a part of the demodulation process. While amplification is important in the overall signal handling, particularly for weakening or distant signals before they are demodulated, it occurs earlier in the signal processing stages rather than during demodulation itself. Thus, amplification does not play a direct role in converting the modulated signal back to its original data format. This makes it the correct choice for something that is NOT a step in the actual demodulation process.
