The process of converting digital data into analog signals for transmission over wireless channels is known as _________.

Modulation refers to the process of converting digital data into analog signals suitable for transmission over wireless channels. It involves techniques like amplitude modulation (AM), frequency modulation (FM), or phase modulation (PM), depending on the specific wireless communication standard. Encoding is the process of converting data from one form to another, which could be digital to digital or analog to digital, but it doesn't specifically refer to the conversion for wireless transmission. Decoding is the reverse process of interpreting encoded data back into its original form. Encryption is the process of securing data by converting it into a form that can only be read or understood by authorized parties, which is not directly related to converting digital data into analog signals for wireless transmission.
