摘要
A digital electronic control apparatus for controlling at least one electronic control element comprises. The apparatus comprises first and second pulse width modulated output signal generators, the frequency of the second signal being different from the first. The second pulse width modulated signal is provided as a function of a digital value determined by at least one of a characteristic and operating condition of the at least one electronic control element. An AND-gate receives the first and second pulse width modulated signals and is capable of producing an output signal for controlling the at least one electronic control element a first and second pulse width modulated signal having a first frequency.
