RE: i need someone to explain for me wh

I'm not sure what you're asking, since PWM stands for Pulse Width Modulation, and PPM stands for Pulse Position Modulation, so the waveforms behave as their names suggest.

For more information, I suggest you read Wikipedia's entriesL

Notice from the examples you provided, PWM has a rising edge at the start of the clock period. To properly get the information from the PPM of your example, you need a independent clock signal or need to re-create the clock using a phase-lock-loop circuit.

Pulse Duration Modulation is a term that isn't used much. PDM has pulses of several fixed widths that are used to define the information. Morse code is an example of PDM.

(OP)
in ppm if you measure the frequency it will be variable
