What is the minimum sample rate required to record a frequency of 96 kHz?
The minimum sample rate required to record a frequency of 96 kHz is 192 kHz. This is because according to the Nyquist theorem, the minimum sampling rate must be at least twice the highest frequency in order to accurately reconstruct the original signal. So for a frequency of 96 kHz, the minimum required sampling rate is double, which equals 192 kHz.
What is the minimum sample rate for a signal frequency of 4kHz?
df
What happens if we sample the signal at sampling frequency nearer to signal frequency?
If you sample at more than the Nyquist frequency (one half the signal frequency) you introduce an aliasing distortion, seen as sub harmonics.
Relative frequency formula?
Probability of event = relative frequency = f/nf is the frequency of the event occurence in a sample of n observances.
Does the size of a sample affect the values of the frequency table?
Yes. If the sample is a random drawing from the population, then as the size increases, the relative frequency of each interval from the sample should be a better estimate of the relative frequency in the population. Now, in practical terms, increasing a small sample will have a larger effect than increasing a large sample. For example, increasing a sample from 10 to 100 will have a larger effect than increasing a sample from 1000 to 10,000. The one exception to this, that I can think of, is if the focus of the study is on a very rare occurrence.
Which value is larger in frequency?
The value with the higher frequency is the one that occurs more often in a dataset or sample population.
What does the sampling theorem tell us concerning the rate or sampling required for an analog signal?
You must sample at 2 x the rate of the analog signal (2 x the analog signal frequency).
Can a minimum data value of a sample be a negative number?
Yes.
What does the term observed frequency refer to?
the frequencies found in the sample data

What are the considerations for the choice of sample size?
Some considerations are:large samples take more time and money to processif the characteristic of interest is very variable then a large sample is required for accurate estimatesif the characteristic of interest is very rare in the population then a large sample is required to ensure that units with that characteristic are included in the samplethe greater the accuracy required of the estimates based on the sample, the larger the sample required.
What is the lowpass filter cutoff frequency that must be used to decimate to reduce the sampling rate from 8kHz to 4kHz?
2kHz - That's the nyquist frequency at a sample frequency of 4kHz.
