How do you find the maximum sample rate?
To get the total maximum sampling rate, you must add all these times together. Do the inverse of this number and you have the maximum sampling period. The interrupts are exact to the precision of units of microseconds, about 5 us on WinNT/2000, and about 10 us on Win9x/Me.
What is the highest frequency component of a signal?
Frequencies “fold” around half the sampling frequency – which is why this frequency is often referred to as the folding frequency. Sometimes the highest frequency components of a signal are simply noise, or do not contain useful information.
Which is the minimum sampling rate for a signal?
The Nyquist rate is the minimum sampling rate satisfying the Kotelnikov-Nyquist-Shannon sampling theorem for a given signal. According to this theorem, it is twice the maximum frequency of the signal being sampled. The Nyquist frequency fn = 0.5 fs also called the Nyquist limit is half the sampling rate of a signal processor.
What is the sampling frequency of 8 kHz?
Per the Nyquist–Shannon sampling theorem, the sampling frequency (8 kHz) must be at least twice the highest component of the voice frequency via appropriate filtering prior to sampling at discrete times (4 kHz) for effective reconstruction of the voice signal.

When is twice the max frequency sufficient to sample a signal?
Twice the maximum frequency is sufficient to sample a signal in theory. The question says: max frequency that human voice can be captured; don’t expect this max frequency (and others) be capture with full accuracy, as suggested in comments by David. In some cases, this can be extended, as long as the bandwidth can be shrunk.
What does it mean when sample frequency is higher than Nyquist rate?
If a signal is sampled at a sampling frequency that is much higher than then the Nyquist rate, this is called oversampling. On the other hand, if one samples a signal at a sample rate below its Nyquist rate, this is called undersampling.
