Pulse-position modulation (PPM) is a form of signal modulation in which M message bits are encoded by transmitting a single pulse in one of 2M possible time-shifts. This is repeated every T seconds, such that the transmitted bit rate is M/T bits per second. It is primarily useful for optical Amplitude_modulation_compared_to_Pulse_position_modulation'systems, where there tends to be little or no multipath interference.

This answer is lifted from response to "Amplitude modulation compared to Pulse modulation", so the original answerer gets credit for a great answer.
PAM-pulse Amplitude Modulation It encodes information in the amplitude of a sequence of signal pulses. PPM-Pulse Position modulation PWM-Pulse Width Modulation.It results in variation of average waveform.
No. Roserade cannot learn Dark Pulse. Sorry.
An electronic pulse generator is used to produce rectangular pulses to power machinery. A microwave is an example of a machine that uses an electronic pulse generator.
Height does not affect pulse rate kthanks.
Mostly tone, although pulse is still available in some areas
It is used for the radio control of model aircraft,boats, cars.
Demodulation the opposite is Modulation And when you put them together you get MODEM Modulation/Demodulation = MODEM
It is a type of Pulse modulation as in PPM the position of pulse of carrier pulse train is varied in accordance with the modulating signal.
It is the taking of the patient's pulse when he/she is in the standing position.
Pulse width mod, pulse amplitude mod, pulse position mod, pulse code mod.
In case of coherent demodulation carrier used for demodulation purpose is in phase and frequency synchronism with carrier used for modulation purpose. For non-coherent demodulation it is not in synchronism.
The width of the pulse in PPM is not important, but is usually very narrow and constant in any given PPM system.
Pulse position modulation offers high noise immunity, efficient use of bandwidth, and easy implementation with digital circuits. This modulation technique is particularly useful in applications requiring high data transmission rates and reliable communication in noisy environments.
demodulation or detection.
probably (the carrier frequency +- the maximum frequency of the pulse train)/(the carrier frequency) but pulses have a lot of harmonics
