What else can I help you with?
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.
What is the blended word for modulation demodulation?
The blended word for modulation and demodulation is "modem." A modem is a device that modulates digital signals into analog signals for transmission and demodulates received signals back into digital form. This process enables communication over various types of networks, such as telephone lines and broadband connections.
How do you generate PPM wave using PWM?
To generate a Pulse Position Modulation (PPM) wave using Pulse Width Modulation (PWM), you first create a series of PWM signals that represent the desired pulse positions for each channel. By varying the timing of the PWM pulses, you encode the position of each pulse within a fixed time frame, ensuring that the pulses do not overlap. The result is a sequence of pulses where the timing of each pulse denotes the information, allowing the PPM signal to be formed. Finally, the generated PPM signal can be outputted to the desired application or device.
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?
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.
What is is origin of the word modem?
MOdulation DEModulation.
What is full meaning of modem?
modulation and demodulation
Which of the following performs modulation and demodulation?
modem
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.
