How the Digital Wireless System Works

Signal waveforms are used to represent sound, and the state of the sound is expressed according to the

width or height of the waveform. Wireless microphones transduce the waveform of audio entering the

microphone into an electrical signal and transmit that signal to a tuner over radio waves. In this event, it is

an analog wireless system that processes the audio signal as it is in the waveform. On the other hand, it is a

digital wireless system that digitally processes the audio signal.

More specifically, in the digital system, after an analog signal (waveform) is transduced into a digital signal (a

signal simplified by binary numbers 0 and 1) and transmitted by radio, the digital signal is demodulated

into an analog signal and then the audio is output. By digitally processing and simplifying the audio

information to be transmitted, the system can have a variety of advantages, including strong immunity to

noise and maintenance of clear sound.

Let’s have a look at the “D/U ratio” of analog-to-digital wireless systems. The D/U ratio refers to the ratio of the

desired (D) signal to the undesired (U) signal (unit: dB). The desired signal represents the level of that signal,

while the undesired signal represents the level of signal interference, otherwise called noise. The D/U ratio

decreases as the undesired signal increases. The D/U ratio can be considered to be a value necessary to

maintaining clear sound in a wireless system.

If a comparison is made of the necessary D/U

ratio between analog and digital wireless systems,

it is 40dB for analog systems and 20dB for digital

systems. From this, it can be seen that the digital

wireless system has an edge over the analog

wireless system by 20dB in terms of necessary

D/U ratio, indicating that the digital system can

maintain clear sound in circumstances where a lot

of undesired signals are present.
