In digital data transmission if the source generates low pass analogue signals with the maximum frequency fm then the correct relation for minimum sampling frequency fs to convert analogue signal to digital signal is:
In digital data transmission if the source generates low pass analogue signals with the maximum frequency fm then the correct relation for minimum sampling frequency fs to convert analogue signal to digital signal is:
1). fs = fm
2). fs = 2 fm
3). fm = 2 fs
4). fs = 3 fm

The sampling frequency for low pass signals is given by Nyquist Criteria
According to which
The signal can be recovered from its samples if the sampling frequency is twice the maximum frequency
Hence
fs ≥ 2 fm
The minimum sampling frequency is given by the equality
fs = 2 fmOther Questions
