According to The Sampling Theorem the sampling frequency for

According to The Sampling Theorem, the sampling frequency for a 10 KHz signal should be sample per second. at least 20.000 at least 10.000 at least 5,000 at most 5.000

Solution

f_s=10KHz

according to sampling theorem to avoid alaising the sampling rate must be at least =f_s/2

                                                                                                                                         =10000/2=5000 samples/sec
