Pulse width is the time in milliseconds that the injector is energized, the duty cycle is the percentage of on-time to total cycle time
The engine computer (pcm) controls the injector pulse. It looks at numerous sensors and switches to calculate pulse width
oxygen sensor
possibly a bad crank sensor
1990 ford ranger 2.3 no injector pulse what causes this
200 Nissan exterra v6 have spark and injector pulse no power to fuel pump
tools u can use are a noid light....or an injector pulser ''TOOL''
Injector pulse is controlled by the ECU. Injectors Have a red wire that is hot. Black wire is controled by computer ground...
The width of the pulse in PPM is not important, but is usually very narrow and constant in any given PPM system.
Pulse width mod, pulse amplitude mod, pulse position mod, pulse code mod.
For the Radar Case: The bandwidth of the pulse is the reciprocal of the Pulse Duration (called Pulse Width) as any filtering needs to be able to detection and follow the pulse shape and its edges. The pulse width is the AM modulation to a Fixed Frequency Carrier Frequency and the AM modulation will be greater bandwidth then the Carrier Frequency. As you are attempting to reject receiving other emissions and noise that do not match your own emissions such that your receiver is "match filtered" to your emissions, your receiver bandwidth will be at least the reciprocal of the pulse width but is lightly to be a smaller bandwidth then the reciprocal of the pulse width.
