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 nonlinear modulation?
nonlinear device modulation is a process which imparts to sinusoidal two or more amplitude levels.
How can you solve limitation of amplitude modulation?
Please define which limitation is being addressed here.
What is the difference between FM and AM radio waves?
AM means Amplitude(=height) modulation, so the frequency stays the same and the message is coded into variations of the strength of the signal. FM stands for Frequency modulation. Here the strength of the signal stays the same and the message is coded into changes in frequency instead.

What modulation does bluetooth use?
It uses GFSK (Gaussian Frequency Shift Keying) modulation technique.
Advantages amplitude shift keying?
Amplitude shift keying (ASK) is simple to implement and requires less bandwidth compared to other modulation techniques. It is also less susceptible to noise interference, making it suitable for applications where signal clarity is important. Additionally, ASK is energy efficient as it allows for power conservation by varying amplitude levels.

Why amplitude shift keyng is called as on offkeying?
Amplitude Shift Keying (ASK) is often referred to as On-Off Keying (OOK) because it represents binary data by switching the amplitude of a carrier signal between two states: a high amplitude (on) for a binary '1' and no amplitude (off) for a binary '0'. This simplicity in representation allows for straightforward modulation and demodulation processes. OOK is a specific form of ASK that directly correlates the presence or absence of signal amplitude to binary values, making it intuitive for digital communication.
What are the advantages of phase shift keying?
The advantage of a binary phase-shift keying is that within a given bandwidth, modulation of higher orders allow to carry higher rates.

What is the difference between AM and ASK?
Amplitude Modulation (AM) and Amplitude Shift Keying (ASK) are both techniques used in communication systems, but they serve different purposes. AM is an analog modulation technique where the amplitude of a carrier wave is varied in proportion to the instantaneous amplitude of the audio signal, typically used in radio broadcasting. In contrast, ASK is a digital modulation scheme where the amplitude of the carrier signal is switched between two levels to represent binary data, making it suitable for digital communication systems. Essentially, AM is used for analog signals, while ASK is used for transmitting digital information.
