PPM is employed in narrowband RF CHANNEL systems, with the position of each pulse representing the angular position of an analogue control on the transmitter, or possible states of binary switch. The number of pulse PER frame gives the number of controllable channels available. The advantage of using PPM for this type of APPLICATION is that the electronics reuired to DECODE the signal are extremely simple, which leads to small, lightweight receiver/decoder units. (Model aircraft reuire parts that are as lightweight as possible).
