| 1. | Since around 1989, 1 bit Nyquist frequency of 1.4112 MHz.
|
| 2. | That means to let the frequency close to Nyquist frequency be the cutoff frequency.
|
| 3. | The Nyquist frequency is therefore 22050 Hz.
|
| 4. | However, considering Hales article it could be sufficient to simply remove the Nyquist frequency.
|
| 5. | This is barely noticeable at low frequencies but is quite evident at frequencies close to the Nyquist frequency.
|
| 6. | Frequency is folded for high speed targets where radial velocity produces a frequency shift above the Nyquist frequency.
|
| 7. | To prevent this an anti-aliasing filter is used to remove components above the Nyquist frequency prior to sampling.
|
| 8. | We will see that IQF of this model will amplify the Nyquist frequency by a factor little less than 5x10 6.
|
| 9. | The bandlimited sawtooths are synthesized from the sawtooth waveform's Fourier series such that no harmonics above the Nyquist frequency are present.
|
| 10. | This is not strictly necessary; for even numbers of points, one includes another cosine term corresponding to the Nyquist frequency .)
