Actually there are four:
- width
- amplitude
- position
- code
Of these four pulse code modulation is digital while the other three are analog.

How is pulse amplitude modulation transmitted?
Generally pulse amplitude modulation (PAM) is trasmitted as a series of DC levels and are mostly used in wired trasmissions (DC is not effective wirelessly).
What is the meaning of FM in FM Radio?
FM means frequency modulation AM means amplitude modulation
What is modulation in music?
modulation within a composition can help define the
What does AM and FM stand for in music?
amplitude modulation & frequency modulation
What does FM stands for?
Frequency Modulation _____________________________________________________________________ fayetville-manlius
What are the types of pulse modulation?
Pulse width mod, pulse amplitude mod, pulse position mod, pulse code mod.
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 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 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 is ppm modulation?
pulse position modulation, used in many RC model aircraft controls.
