Digital audio conferencing systems are produced for analog audio conferencing systems.
The digital audio conferencing system converts the analog-represented audio signal into a digital audio signal composed of a number of binary numbers 1 and 0 by sampling and quantization. The digital signal is transmitted in a digital system. The advantage of the digital signal is that the signal is not distorted within the effective distance. It has good anti-noise ability and is not susceptible to attenuation. When the signal is weakened, it can be recovered without distortion. Easy to handle by computer, the design of the chip is relatively simple. Therefore, the digital audio conferencing system is getting a high-speed development and has gradually become the mainstream of the conference market.
