ABSTRACT:
A method and apparatus for detecting and displaying automotive fuel injector voltage signal pulse width which includes signal detection circuits for capturing the rising and falling edges of an input signal having positive and negative voltage swings is disclosed. Upon detecting a rising edge or a falling edge of a positive or negative voltage of the input signal, a corresponding software routine is executed to carry out the process of measuring the pulse width of a pulse of the input signal. The measured pulse width is then displayed in numerical and/or histogramic formats.
