What is ppm modulation?

pulse position modulation, used in many RC model aircraft controls.


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 difference between pulse width modulation and pulse position modulation?

Frequency modulation, as the name suggests, modulates the carrier by changing the frequency of the signal emitted. Pulse width modulation, changes the on-time of a square wave, but leaves the frequency of the carrier wave unchanged. So, in frequency modulation, the frequency will vary between, say, 80kHz and 120kHz with a constant power level, but in pulse width modulation, the frequency will stay at 100kHz, but the on-time (the length of each pulse) will vary, hence the power level will vary accordingly.


Difference between analog modulation and digital modulation?

Analog Pulse modulation is discreet in time but the formation is transmitted in continuous form. In digital pulse modulation, not only the time axis is discreet but the information is also in digital form. Examples of Analog PM are PAM and PTM i.e pulse amplitude and pulse time modulations respectively. Examples of Digital PM are PCM and PDM i.e pulse code and pulse delta modulations respectively.


How regenerative repeater work in pulse code modulation?

Regenerative Repeater is used for the PCM (Pulse code modulation ) it amplifies the signal because the effect of the channel over the signal .

What term means changing the characteristics of a signal as when a modem changes a digital pulse into an analog audio signal?

Demodulation the opposite is Modulation And when you put them together you get MODEM Modulation/Demodulation = MODEM


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 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 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 is opposite of modulation?

demodulation or detection.


What is ppm modulation?

What are the types of pulse modulation?

Pulse width mod, pulse amplitude mod, pulse position mod, pulse code mod.


What is is origin of the word modem?

MOdulation DEModulation.


Which of the following performs modulation and demodulation?

modem


What is full meaning of modem?

modulation and demodulation


Is the computer is input or output?

modulation and demodulation


What are the electronic communication?

its nothing but modulation and demodulation. modulation of the message is done in transmitter side and demodulation is done at receiver side and retrieving the original message.
