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

What else can I help you with?
What are the types of pulse modulation?
Pulse width mod, pulse amplitude mod, pulse position mod, pulse code mod.
What is the advantage of ppm over pwm and Pam?
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.
What is need of space vector pulse width modulation?
due to space vector modulation we can eliminate the lower order harmonics
What are the differences between natural sampling and pulse amplitude modulation?
In pam dc shift is present which will not present in natural sampling.
Application of pulse width modulation?
PWM finds use in power applications like dc motor speed control
What are the advantages of pulse position modulation?
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.
What type of modulation is pulse position modulation and why?
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.
What are advantages of pulse amplitude modulation?
carry information as well as to generate other pulse modulations.
What is the carrier signal used for pulse modulation?
In pulse modulation, the carrier signal is typically a continuous analog waveform, such as a sine wave or square wave, that serves as the basis for transmitting information. The modulation process involves varying certain properties of this carrier wave—such as its amplitude, width, or position—according to the information signal. This modulation allows the information to be encoded and transmitted efficiently over various communication channels. Common types of pulse modulation include Pulse Amplitude Modulation (PAM), Pulse Width Modulation (PWM), and Pulse Position Modulation (PPM).
What is ppm modulation?
pulse position modulation, used in many RC model aircraft controls.
What are the types of pulse modulation?
Pulse width mod, pulse amplitude mod, pulse position mod, pulse code mod.
How do you calculate the width of pulse in pulse position modulation?
The width of the pulse in PPM is not important, but is usually very narrow and constant in any given PPM system.
What is pulse position modulation and demodulation?
It is used for the radio control of model aircraft,boats, cars.
What is the bandwidth of pulse position modulation?
probably (the carrier frequency +- the maximum frequency of the pulse train)/(the carrier frequency) but pulses have a lot of harmonics
What is the difference between Pam ppm and pwm in digital communication?
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.
What is pulse position demodulation?
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.
What is the difference between pulse code modulation and delta modulation?
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.
