Can tdm and fdm be used at the same time in a communication system?

[Answer]: The principle of C TDM (Time-Division Multiplexing) method is to divide the time into small time slots. Each time slot is occupied by a signal, and the user of each time division multiplexing is in each T The time slot occupied by a fixed serial number in the DM frame, and the time slot occupied by each user appears periodically.

In data communication systems or computer network systems, the bandwidth or capacity of the transmitted media is often greater than the demand for transmitting a single signal. In order to effectively use the communication line, it is hoped that one channel transmits multiplexing signals at the same time, which is the so-called multiplexing technology (Multiplexing ).

In data communication systems or computer network systems, the bandwidth or capacity of the transmission medium often exceeds the demand for transmitting a single signal. In order to make effective use of communication lines, it is hoped that one channel can transmit multiplex signals at the same time, which is the so-called multiplexing technology.

How to choose the TDM system for manufacturing enterprises

1. Therefore, enterprises should choose TDM suppliers with excellent business credibility, strong development strength and experience in implementation.

2. TDM (test data manager) test data management system. TDM is a data management system, which is an integral part of product life cycle management (PLM).

3. TDM is the time division reuse mode. Time division multiplexing refers to a technology that transmits multiple digital data, voice and video signals on the same communication media at the same time through cross-bit pulses in different channels or time slots. Tdm service is actually a kind of communication service.

4. DCS, material supply system, human resources system, etc.; 4) It must be flexible enough. When the user's business and needs change, it can be conveniently modified and easy to upgrade. Shenzhou Universal Experimental Data ManagementThe application of the system AppTDM in the wind tunnel test is relatively mature, and you can contact the corresponding engineer for specific solutions.

What are the benefits of the TDM system

1. TDM divides the channel into different time slots in time, inserts different pulse signals on different time slots, and realizes the multiplexing of multiple signals in the time domain in turn.

2. In a communication system, two technologies can indeed be used at the same time, TDM and FDM. TDM is a way to share time as a resource. It can divide time into different time slots, and each time slot is assigned to different users or data streams.

3. TDM provides users with business process management;Test process monitoring; data collection, analysis, mining of test resources, knowledge, standard management and integration with other information system interfaces. Adopting Shenying TDM can improve the utilization rate of test data, accumulate test-related knowledge and experience, and comprehensively improve the level of test digital management.
