In this example, fs is the sampling rate, and 0.5 cycle/sample × fs is the corresponding Nyquist frequency. The black dot plotted at 0.6 fs represents the amplitude and frequency of a sinusoidal function whose frequency is 60% of the sample rate. The other three dots indicate the frequencies and amplitudes of three other sinusoids that would produce the same set of samples as the actu… WebThe wider this transition band is, the easier and more economical it is to make an anti-aliasing filter. The 44.1 kHz sampling frequency allows for a 2.05 kHz transition band. In addition, 44,100 is the product of the squares of the first four prime numbers (2^2 * 3^2 * 5^2 * 7^2) and hence has many useful small factors.
