Claim:
1. A method of assessing a pulse-width-modulated signal, the method comprising: applying a pulse-width-modulated signal to be assessed to a first input of a microcontroller, applying a signal that depends on the pulse-width-modulated signal to be assessed to a second input of the microcontroller for assessment by the microcontroller, applying the pulse-width-modulated signal to be assessed to a voltage divider to produce, from the pulse-width-modulated signal, a signal that depends on the pulse-width-modulated signal to be assessed, determining, via the microcontroller, for the pulse-width-modulated signal to be assessed and for the signal that depends on the pulse-width-modulated signal to be assessed, a time interval between signal edges of the respective signals, and accessing the pulse-width-modulated signal to be assessed on a basis of a difference between the time interval between the signal edges in the pulse-width-modulated signal to be assessed and the time interval between the signal edges in the signal that depends on the pulse-width-modulated signal to be assessed.
