The LED can be linearized within the interval [c, -c], where c dentotes the pre-specified clipping level
. The LED input signal [x.sub.LED] is obtained from [x.sub.pts] after clipping process further reduce the PAPR.
Higher clipping level
values can be applied to the signal for reducing the clipping noise at the expense of increasing the electrical power of the signal.
It adopts the Schroeder phases as the initial phases and uses variable clipping level
based on logarithmic function in the iteration procedure.
This is not a surprise for those who have ever checked the actual CF of the shaker table acceleration after setting up a certain clipping level
for the drive signal.
I have no problem with someone saying that an amp sounds clean and transparent to them (I did so with all of my amplifier reviews), because any decently designed amp will sound just that way, at least below the clipping level
and with normal-type speaker loads.
If the peaks are kept just below the clipping level
, the average efficiency will correspond approximately to the efficiency of the PA at the mean power level, which can be several dBs lower than the PEP.
The piecewise linear companding transform, presented in , and its inverse are defined using three parameters: clipping level
[[alpha].sub.c], inflexion point [[alpha].sub.i] and slope k.
WORDLENGTH OF THE TRANSMITTED SYMBOLS AND OPTIMAL CLIPPING LEVEL
however, if the maximum amplitude of a(t) [a.sub.MAX] is greater than the clipping level
of the amplifier [a.sub.SAT], clipping occurs, distorting the output signal.
The Omnia.11 has a new software release that now includes Frank Foti's Pepino Clipper Mode 2, the next evolution in top-tier clipper technology designed to preserve brightness at aggressive clipping levels
. Now featuring Clipper "Sparkle" Control, a Bass Clarity enhancer added to Bass EFX, and new Bass Sensitivity controls to give broadcast engineers and program managers more power than ever before.
Additional legalisation features include automatic luma overshoot and undershoot suppression together with luma and chroma gain, black level adjustment, hue rotation, adjustable clipping levels
and soft-clipping-knee levels.
The clipping levels
in renewed annually within the framework of the appropriations (0-2 units / year).
