Best Answer

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

ADVANTAGES


-Low Noise Susceptibility


-Repeatability


-Storage


-Encoded Signal


DISADVANTAGES


-PCM requires very complex encoding and quantizing circuitry.

-PCM requires a large bandwidth compared to analog signals.

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.

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 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 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.


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.
