Time-division multiplexing (TDM) is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time according to agreed rules, e.g. with each transmitter working in turn.

2023年11月15日 · 时分复用 (Time Division Multiplexing, TDM) 是一种将多个数据流在同一个通信介质上同时进行传输的方法，其基本原理是通过时间轴的切割，使得每个数据流在一定时间内占据所有的传输资源。

Time-division multiplexing or TDM definition is; a multiplexing technique that is used to transmit two or above streaming digital signals above a common channel. In this type of multiplexing technique, incoming signals are separated into equivalent fixed-length time slots.

综合不少厂商的数据手册，笔者发现，在应用PCM音频接口传输单声道数据（如麦克风）时，其接口名称为 PCM；双声道经常使用 I2S；而 TDM 则表示传输两个及以上声道的数据，同时区别于I2S特定的格式。

2023年7月13日 · Time division multiplexing (TDM) is defined as a technique used to transmit multiple signals simultaneously over a single communication channel. In TDM, the channel is divided into several time slots, and each signal is transmitted during its allocated time slot.

2024年7月1日 · Time Division Multiplexing (TDM) is a method employed in telecommunications and computer networks for transmitting multiple signals through a single communication channel. It optimizes bandwidth usage by partitioning the channel into distinct time slots, enabling several users or data streams to utilize the same physical medium efficiently.

2024年4月7日 · Time-Division Multiplexing (TDM) is a foundational technology in telecommunications that optimizes the use of bandwidth by dividing a single physical communication channel into multiple time slots. This method allows several data streams to share the same transmission medium while keeping the integrity of each separate stream intact.

Definition: A multiplexing technique by which multiple data signals can be transmitted over a common communication channel in different time slots is known as Time Division Multiplexing (TDM). It allows the division of the overall time domain into various fixed length time slots.

2025年1月14日 · TDM：如果应用中需要传输多个音频通道数据（如多声道音频系统、环绕声），TDM更适合，尤其适用于广播、音频交换和音频处理系统。 PDM：适用于低功耗的应用，如数字麦克风、音频传感器等，特别适合需要高信噪比并且对音频质量要求不那么高的场合。 PCM：如果音频系统要求高质量、低延迟音频传输，PCM是优选方案，适用于CD、电话通信和电视等对音质有较高要求的应用。 _pdm pcm.

2017年6月14日 · Time-Division Multiplexing (TDM) is a convenient method for combining various digital signals onto a single transmission media such as wires, fiber optics or even radio. These signals may be interleaved at the bit, byte, or some other level.
