Time and sample rate for QAM I am trying to understand how to get time as I already have sample rate. I want to draw a graph of sample rate vs time. I have information such as carrier frequency, channel bandwidth. Can that be used to get time. 

So far, I have understood this: Samples per symbol and number of symbols for QAM

In order to get the time, I would need to do this:

T = 1/Samples per symbol

Would this be correct.
Consider you have a bandwidth of B. The sampling rate $F_s$ which is related to B using the relation $F_s &gt; 2B$. Now the sample time is $\frac{1}{F_s}$. So if you have N samples  then total time is $\frac{N}{F_s}$

Is that what you are looking for?
