Detroughing Function telecom.

Добрый день!

Подскажите, как корректно перевести указанное выражение в следующем контексте:
Detroughing Function
Selects the mathematical function describing the detroughing.
The following functions are available:
● f(x) = x + d*e-x/d
● f(x) = 1 - (1 - d)*cos(x*pi/2)
● f(x) = d + (1 - d)*xa
where:
● x = normalized input power Pin of the power amplifier
● d = Detroughing Factor (d)
● a = Exponent (a)

Судя по всему, это одна их функций, определяющих форму кривой на графике:

You can select the way you define the shaping function:
● predefined simple linear functions
● detroughing function with a configurable factor
● polynomial function with up to 10 polynomial coefficients

Всем спасибо!

Ни у кого не появилось вариантов?

Может, лучше перевести остальное и показать специалисту в этой сфере. Может, ему будет даже легче предложить вариант по смыслу, а вам потом проверить.

In such ET architectures, the integrity of the peaks of the envelope waveform must be maintained, whereas the integrity of the troughs of the envelope waveform is not critical, provided sufficient voltage headroom is maintained. The troughs of the waveform are associated with a high voltage slew rate. Therefore, in some examples of the invention, the modulated power supply 528 provided to the PA 424 may be referenced to a modified envelope waveform, with the troughs of the envelope waveform clipped or removed, i.e. the depths of the envelope waveform troughs are reduced. Removing the troughs reduces the high-frequency components from the voltage waveform, whilst increasing the DC content of the voltage waveform. This concept will be hereinafter termed `de-troughing`.
