An unfortunate consequence of this is that at some critical frequency, the phase of the amplifier's output = " 180?compared to the phase of its input signal.
12.
Increasing the frequency beyond the critical frequency creates minimal further improvement in heating efficiency, although it is used in applications that seek to heat treat only the surface of the workpiece.
13.
In astrophysics, x is usually a ratio of frequencies, that is, the frequency over a critical frequency ( critical frequency is the frequency at which most synchrotron radiation is radiated ).

15.
Electrical transmission lines can be used to describe acoustic tubes and ducts, provided the frequency of the waves in the tube is below the critical frequency, such that they are purely planar.
16.
The existence of the critical frequency is the result of electron limitation, " i . e ., " the inadequacy of the existing number of free electrons to support reflection at higher frequencies.
17.
In multirate filters, the number of coefficients by taking advantage of its bandwidth limits, where the input signal is downsampled ( e . g . to its critical frequency ), and upsampled after filtering.
18.
The " ? " c are the critical frequencies ( the frequency where cut-off begins ) and the " ? " " are the poles of attenuation in the stop bands.
19.
From Eq . ( 10 ), we observe that the radiation intensity is negligible for \ xi \ gg 1 . " Critical frequency " is defined as the frequency when } } and 0 } }.
20.
For example, if a Dirac delta impulse occurs exactly at a sampling point and is ideally lowpass-filtered ( with cutoff at the critical frequency ) per the Nyquist Shannon sampling theorem, the resulting discrete-time signal will be a Kronecker delta function.
