YES!
'digital' technology means it uses a digital coding system for the transmission of the data --- this ought to be reliable and foolproof, and relatively robust (against interference etc.) compared with the alternative (old!) 'analogue' technology
'proportional' means that the controlled function will move (etc.) to an extent that can vary continuously so as to be in proportion to the position of the control lever --- for example, if you push the 'accelerator' joystick to 50% of its travel, the car's accelerator will move to the 50% position. This is as distinct from the alternative 'binary' or 'digital' (confusingly, but in a different meaning here!) form, where the signal has only 2 possible states --- e.g. 'On' or 'Off' --- as might be used for a simpler function like Forward / Reverse gear, for example.
