Sentence examples for frequency present in from inspiring English sources

The Nyquist sampling theorem showed that the sampling rate must be at least twice the highest frequency present in the sample in order to reconstruct the original signal.

The sampling theorem (Appendix D) says that we will have no aliasing due to sampling as long as the sampling rate is higher than twice the highest frequency present in the signal being sampled.

If the sampling frequency is much higher than the maximum frequency present in the signal that will be interpolated.

where T s is the sampling period and Ωmax represents the maximum frequency present in the signal.

Of course, the obvious way (and the simplest way) to avoid aliasing when there is no extra information available is to require two times the maximum frequency present in the signal.

The most famous theorem is often attributed to Shannon [5, 6] (but usually called Nyquist rate) and says that the sampling rate must be twice the maximum frequency present in the signal in order to perfectly recover the signal.

Over-represented motifs were identified according to their frequency presented in BT×623 and Keller (Additional files 2 and 3).

This helical scan method allows the wide range of frequencies present in a video signal to be recorded on a slow-moving tape.

The precise frequencies present in the vibrations can then, in principle, be used to reconstruct the word being spoken.

Several such chambers, each tuned to one of the predominant frequencies present in the exhaust stream, effectively reduce noise.

Time-varying filters, on the other hand, can generate audible sideband images of the frequencies present in the input signal (when the filter changes at audio rates).
