Consider the following statements regarding Time-Division Multiplexing (TDM):1. The information from different measuring points is transmitted serially on the same communication channel.2. It involves the transmission of data samples rather than continuous data transmission.3. It is especially useful when telemetering fast-changing, high bandwidth data.Which of the above statements are valid in respect to TDM?
