MATLAB: Finding the sampling frequency from the following

Question

Hi everyone,

I have to work out the sampling frequency. I have set up a vector of time values with 128 elements sampled at twice a second. The signal has to be calculated with five cycles in 63.5s and the code for that is:

t = 0:0.5:63.5; yt = sin(2*pi*t*5/63.5);

How do I get the sampling frequency from this information?

Thanks!

Answer 1

Sampling frequency is 1 divided by sample rate.

1 / (M seconds per sample) = ? samples per second

and samples per second is Hz .
