A digital signal converter converts digital data into an analog signal for transmission over traditional radio frequency (RF) communication channels. The conversion process involves several steps, including quantization, encoding, and modulation. Quantization is the process of converting digital signals into discrete values or levels, while encoding refers to the assignment of a specific code or symbol to each level. Modulation is the process of varying the characteristics of an analog signal, such as amplitude or frequency, in accordance with the information in the digital signal.
