Read PWM Signal from a RC-Receiver

Note that the radio control signal isn[ch8217]t really PWM, (although it is often called that) it[ch8217]s a form of pulse position modulation (PPM).

I think you misunderstood me.

I want to read the signal that comes FROM the receivers output socket to ONE servo. I don't want to read the complete transmission for ALL channels.

According to wikipedia and other sources this should be a PWM signal. I havent found anything here too.
But then i looks that i have to create/copy code to do that.

One more idea:
Couldn't i use a capacitor and a resistor to convert this signal to an anlog signal???
Maybe i have to compare this signal to with the level of the receiver battery.
