ABB LDMUI-01 digital network for transmission

To achieve digital communication, it is necessary to convert the analog signal emitted by the sender into a digital signal, a process known as “analog-to-digital conversion”. The most basic method for digitizing analog signals involves three processes. The first step is “sampling”, which involves discretizing continuous analog signals, usually by extracting samples of analog signals at equal time intervals. The second step is “quantization”, which transforms the analog signal sample value to the closest digital value. Although the sampled values are discrete in time, they are still continuous in amplitude, and the quantization process is to transform the continuous sampling in amplitude into discrete. The third step is “encoding”, which is to represent the quantized sample signal with a set of binary digital codes, ultimately completing the digitization of the analog signal. Digital signals are sent to the digital network for transmission. The receiving end is a restoration process that converts the received digital signal into an analog signal, known as “data touch transformation”, in order to reproduce sound or image.
If the signal emitted by the sending end is originally a digital signal, there is no need for analog-to-digital conversion process, and the digital signal can be directly transmitted into the digital network.
Due to the rapid increase in demand for various communication services, digital communication is rapidly developing towards miniaturization, intelligence, high-speed, and large capacity, and will eventually replace analog communication.
