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.
Why ppm is said to be better than pwm system?
PPM (Pulse Position Modulation) is often considered better than PWM (Pulse Width Modulation) in certain applications because it provides a more robust signal against noise and interference. PPM encodes information in the position of pulses rather than their width, making it less susceptible to timing errors. Additionally, PPM can allow for more efficient use of bandwidth in communication systems, as it can transmit multiple channels within the same signal. This can lead to improved performance in applications like remote control systems and telemetry.
Pwm generatoe circuit?
Pulse Width Modulation generator circuit is mainly used in controlling DC motors in connection with the constuction of different kinds of robotics.It basically tests a robots motor funtion, which can be done before the robot is built.
Can audio signals be modulated in infrared?
yes of coarse but use some modulating technique such as pam,pwm or ppm this will increase distance between reception and transmission without much distortion
What is dcdc chopper?
A chopper or DC-DC converter is a circuit or technique used to convert a constant DC signal into a variable DC signal where by using switching technique known as PWM(pulse width modulation). A chopper is a static device that converts dc input into dc output voltage directly. A chopper may be thought of as an ac transformer since they behave the same.
What is PPM and PWM?
PPM- Parts Per Million I'm not aware of PWM
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 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.

Which modulation is used with digital data?
-- PSK -- DPSK -- 16, 32, 64, 128, and 256 QAM
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 PWM chip?
A PWM (Pulse Width Modulation) chip is an integrated circuit designed to generate PWM signals, which are used to control the amount of power delivered to electronic devices. By varying the width of the pulses in a fixed time period, the chip can adjust the average voltage and current supplied to components such as motors, LEDs, and heaters. PWM chips are commonly used in applications like motor speed control, light dimming, and signal modulation due to their efficiency and precision.

What is DC chopper?
chopper use a ststeing perpose..... dc means direct current that is low voltage

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.
