to do the same with PPM you will need several frames of data before you can make any assumption of errors. Also a valid PCM frame can be recovered IMMEDIATELY wheras a PPM Signal would have to be consistent for many frames before you can make that assumption.
Totally wrong. The PPM error detection see an error immediately, it does not require subsequent frames. Similarly, it comes out of failsafe on the very first good frame. You clearly think the error detection is based on comparing data from one frame to the next, which is not correct.
