Original post by uberteknikYes, that's Time Division Multiplexing:
As you have correctly identified, each 6uS signal must comprise 3 bit words (signal time / sampling period) = 6x10-6/ 2x10-6 = 3 samples per signal.
In this example of TDMuxing, each signal is allocated a recurring 6uS window and the question states there are only two signals. So the words must alternate. If there were 6 channels say, then they would be muxed as recurring 6 x 6uS words: 3-bit channel1, 3-bit channel 2, 3-bit channel 3 etc.
In reality, there are no hard and fast rules unless the data stream must comply with a defined international specification so that diferent manfacturers' equipment can communicate with each other as well as decode the data stream.
For this question you still have to make assumptions, For instance the serial stream is transmitted MSB to LSB in order to reconstruct the data.
Given that the raw serial data stream is
(put spaces in as you go to mimimise reading error):
101 101 011 001 000 101 010 010
Then reconstruct the channel data by alternately breaking out.
i.e. the data stream is structured c1w1, c2w1, c1w2, c2w2, c1w3, c2w3 etc. where c = channel, w = 3-bit word.
Channel 1: 101 011 000 010
Channel 2: 101 001 101 010
