advantage-its a base for all the digital modulation technique
disadvantage-
1.since amplitude keeps varying so there is noise associated with it.
2.due to nyquist criteria its require high bandwidth.
3.due to amplitude variation peek power of receiver also varies with it

-Encoded Signal
DISADVANTAGES
-PCM requires very complex encoding and quantizing circuitry.
-PCM requires a large bandwidth compared to analog signals.
What are the advantage of polsu amplitude madulation
.
An advantage of pulse position modulation, or PPM, would be that the receiver does not need to use a phase-locked loop for tracking. A disadvantage of PPM is its sensitivity to interference.
Pulse width mod, pulse amplitude mod, pulse position mod, pulse code mod.
PPM is a type of pulse modulation where messages are sent using single pulses. PWM is a type of modulation which conforms to the pulse. PAM is a type of modulation in which the information is encoded into a series of pulses.
due to space vector modulation we can eliminate the lower order harmonics
In pam dc shift is present which will not present in natural sampling.
PWM finds use in power applications like dc motor speed control
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.
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.
carry information as well as to generate other pulse modulations.
pulse position modulation, used in many RC model aircraft controls.
Pulse width mod, pulse amplitude mod, pulse position mod, pulse code mod.
The width of the pulse in PPM is not important, but is usually very narrow and constant in any given PPM system.
It is used for the radio control of model aircraft,boats, cars.
probably (the carrier frequency +- the maximum frequency of the pulse train)/(the carrier frequency) but pulses have a lot of harmonics
The difference between pulse code modulation and delta modulation is that pulse code modulation is a method of encoding audio information digitally while delta modulation is a method that converts analog to digital signal.
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.
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.Read more: Amplitude_modulation_compared_to_Pulse_position_modulation'This answer is lifted from response to "Amplitude modulation compared to Pulse modulation", so the original answerer gets credit for a great answer.
