What’s the relationship between samples and bits

bit ratesamplingtransmitter

I was talking to a friend today that I have a transmitter which is capable of sending 128 samples/second. Note that each sample is a voltage level represented by a floating point decimal. He then insisted that I call it a 7 bit system since 128 is 2^7.

What useful information can I possible get from representing the samples/second in number of bits? What can each bit physically represent?

Your transmitter can send 128 samples of data. Each sample contains a x number of bits depending on your transmitter. If your transmitter is a 8 bit transmitter then you can send 128 times a 8 bit sample in one second.
