Final answer:
PPM (Pulse Position Modulation) interacts with APM (Automated Process Management) through a communication protocol.
Step-by-step explanation:
PPM (Pulse Position Modulation) interacts with APM (Automated Process Management) through a communication protocol. This protocol allows PPM to transmit data to APM in a structured and organized manner. For example, in wireless communication systems, PPM can be used to modulate the position of a pulse within a time slot, while APM manages the overall system operations and processes the received data efficiently.
