Characteristics Of The PWM Signal
Characteristics Of The PWM Signal
Frequency
The actual frequency does not tell us anything about the value of the information carried by the cable but it can confirm that contact has been
established with transmitting control modules and we can check whether the frequency is within reasonable limits.
Pulse Length
At 100 Hz there are 100 pulses a second, which means that the maximum pulse length is 1/100th of a second, i.e. 10 milliseconds. The pulse
length at 100 Hz can therefore vary between 0 and 10 milliseconds.
