Assume your sampling frequency (fs) is 500 Hz. If you want to capture the 50Hz signal for 5 seconds, calculate the number of samples (N) at the assumed fs to get the desired 5 seconds of data.

Answer:

N = 2500

Explanation:

By definition, the sampling frequency (fs) is:

[tex] f_{s} = N / T [/tex]

where N: is the number of samples and T: is the time

Hence, the number of samples at the sampling frequency, 500 Hz, to get 5 seconds of data is:

[tex] N = f_{s} \cdot T = 500 s^{-1} \cdot 5 s = 2500 [/tex]
