Abstract
A system for equalizing amplitude tilt distortion in a signal includes an amplitude tilt maker and an amplitude tilt sensor. The input signal is split in the amplitude tilt maker between a signal through path and a phase shifted, time delayed signal path. The phase shifted, time delayed signal then passes through a voltage controlled attenuator. Combining the phase shifted, time delayed signal with the signal that travels along the signal through path provides the amplitude tilt. The tilt can be adjusted by changing the control voltage to the attenuator in order to compensate for amplitude tilt distortion in the input signal. The voltage controlled attenuator is controlled by the amplitude tilt sensor, which 'senses' the tilt using a loop signal from the amplitude tilt maker.
