What else can I help you with?
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
How does differential pulse code modulation lower the bit rate of transmitted signals?
It signals the difference between successive sample sizes
What are the three types of pulse modulation?
Actually there are four:widthamplitudepositioncodeOf these four pulse code modulation is digital while the other three are analog.
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 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.
Explain with diagram the technique Pulse-amplitude modulation?
Explain with diagram the technique Pulse-width modulation?
How many types of pulse width modulation techniques are there?
as many as there are ways to place points on a line segment
What is the digital pulse modulation?
There are 3 main types of digital pulse modulation:Pulse time modulation (PTM), somewhat similar to analog phase modulation.Pulse width modulation (PWM), the width of the pulse represents the signal.Pulse code modulation (PCM), serial transmission of binary bits forming numeric or character codes that represent the signal.All of these can be modulated on an RF carrier using any of the standard modulation techniques: AM, FM, Phase Modulation, etc. One advantage with AM digital pulse modulation techniques over AM analog is that the carrier can be 100% modulated, which cannot be done with analog, thereby allowing significant reductions in transmitter power without loss of coverage range. Sometimes FM digital pulse modulation techniques are referred to as Frequency Shift Keying (FSK). A very complex method of combining Phase Modulation and AM to increase the bit density of digital pulse modulation on an RF carrier is called Quadrature Amplitude Modulation (QAM).

What is the difference between space vector modulation and pulse width modulation?
There is no difference.
What do you mean by pulse width modulation?
pulse width modulation is nothing but changing on and off time period of a waveform without changing its frequency
What modulation is used in telegraphy system?
pulse code modulation method used a telephony.
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 ppm modulation?
pulse position modulation, used in many RC model aircraft controls.
