    MN004528A01-AF Overview Chapter 2 Overview To achieve a high spectrum efficiency, the radio uses digital modulation technology and sophisticated voice-compression algorithm. The voice of the person speaking into the microphone is converted into a digital bit stream consisting of zeros (0) and ones (1). This stream is then modulated into a radio frequency (RF) signal, which is transmitted over-the-air to another radio.
