You are sampling a signal which consists of a mixture of 160, 164 and 168 Hz sinusoids and which you want to resolve in your FFT. If you are storing 4096 samples, what is the range of sampling frequencies you can use such that you don’t violate Nyquist theorem and still meet or exceed the needed resolution when you perform the FFT operation on the full set of collected data.
a. any frequency greater than or equal to 336 Hz
b. less than or equal to 16384 Hz but greater than 336 Hz
c. less than or equal to 4096 but greater than 336 Hz
d. less than or equal to 8192 Hz but greater than 336
