What is the carrier signal used for pulse modulation?
In pulse modulation, the carrier signal is typically a continuous analog waveform, such as a sine wave or square wave, that serves as the basis for transmitting information. The modulation process involves varying certain properties of this carrier wave—such as its amplitude, width, or position—according to the information signal. This modulation allows the information to be encoded and transmitted efficiently over various communication channels. Common types of pulse modulation include Pulse Amplitude Modulation (PAM), Pulse Width Modulation (PWM), and Pulse Position Modulation (PPM).
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.
How many types of pulse width modulation techniques are there?
as many as there are ways to place points on a line segment
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 effect does pulse width inflict on Time division multiplexing signal?
In Time Division Multiplexing (TDM), pulse width directly affects the signal's ability to maintain data integrity and minimize inter-symbol interference. A narrower pulse width allows for more channels to be time-multiplexed within the same bandwidth, but it increases the risk of overlapping and distortion, especially in noisy environments. Conversely, a wider pulse width can improve signal clarity and reduce interference, but it limits the number of channels that can be multiplexed. Therefore, optimizing pulse width is crucial for balancing channel capacity and signal quality in TDM systems.

What is pwm?
PWM stands for Pulse Width Modulation. It is a technique used to encode a message into a pulsing signal by varying the width of the pulse relative to a fixed time frame. PWM is commonly used in controlling the speed of motors, regulating power to LEDs, and generating analog voltage levels from digital signals.
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 is the difference between Pam ppm and pwm in digital communication?
PAM-pulse Amplitude Modulation It encodes information in the amplitude of a sequence of signal pulses. PPM-Pulse Position modulation PWM-Pulse Width Modulation.It results in variation of average waveform.
What is the Application of ppm and pwm?
PPM (Pulse Position Modulation) is used in digital communication systems to encode information by varying the position of the pulses in a periodic signal. PWM (Pulse Width Modulation) is commonly used in controlling the power delivered to electronic devices like motors, LEDs, and amplifiers by varying the width of the pulses in a periodic signal.
What are the types of pulse modulation?
Pulse width mod, pulse amplitude mod, pulse position mod, pulse code mod.
How do you calculate the width of pulse in pulse position modulation?
The width of the pulse in PPM is not important, but is usually very narrow and constant in any given PPM system.

Which modulation technique is most prone to noise PWM or AM?
AM = Amplitude Modulation and is more prone to noise because the signal amplitude caries the intellegence, Noise changes this easily. PWM is Pulse Width Modulation and noise does not change the width of the pulses, though it may introduce other pulses. Therefore the original intellegence is still recoverable.
