\item[Modulation pre-emphasis and slew-rate control.] Pre-emphasis might be necessary to ensure an adequate
Signal-to-Noise ratio (SNR) at the receiver. Slew-rate control and other shaping measures might be necessary to
reduce the impact of these sudden load changes on the transmitter's primary function (say, aluminium smelting)
and to prevent disturbances to grid components.
