PAM PWM PPM Modulation/Comparison of PAM, PWM and PPM/PAM Vs PWM Vs PPM/ Pulse Modulation Techniques
This video discusses detailed comparison between PAM, PWM and PPM pulse modulation techniques, i.e. PAM Vs PWM Vs PPM on the basis of following parameters- Definition of PAM, PWM and PPM Waveforms Variable Parameter Bandwidth Power Noise interference Similarity with Continuous Wave modulation Synchronization between transmitter and receiver etc. we discussed different types of pulse modulation techniques, like Pulse Amplitude Modulation (PAM), Pulse Width Modulation (PWM), Pulse Position Modulation (PPM) and Pulse Code Modulation (PCM). In this post we will deal with the comparative study of PAM, PWM and PPM. Here we will compare these 3 different pulse modulation techniques, on the basis of various parameters. 1.Definition PAM- In pulse amplitude modulation, the amplitude of the pulsed carrier wave is varied according to the modulating signal value. PWM- In pulse width modulation, the width of pulsed carrier is varied as per the value of the modulating signal. PPM- In pulse position modulation, the position of the pulsed carrier is varied as per value of modulating signal. 2.Waveform Waveform of PAM, PWM and PPM is given in the image below. Click on the image to enlarge it. 3.Variable Parameter Of The Carrier PAM- Amplitude PWM- Width PPM- Position 4.Where The Information Is Present PAM- In amplitude variations of the pulses PWM- In width variations of the pulses PPM- In position variations of the pulses 5.Type of Carrier Wave Used PAM- Train of pulses PWM- Train of pulses PPM- Train of pulses 6.Bandwidth PAM- Bandwidth depends on the width of the pulse Bandwidth requirement is low PWM- Bandwidth of the channel depends on rise time of the pulse Bandwidth requirement is high PPM- Bandwidth depends on rise time of the pulse Bandwidth requirement is high 7.Instantaneous Power PAM- Power varies due to change in amplitude of the pulses PWM- Instantaneous power varies due to change in width of the pulses PPM- Instantaneous power is constant due to constant amplitude and width of the pulses 8.Noise Interference PAM- Noise interference is maximum and it is difficult to remove noise PWM- Noise interference is less due to constant amplitude PPM- Noise interference is less due to constant amplitude 9.Similarity With Continuous Wave Modulation PAM- Similar to Amplitude Modulation (AM) PWM- Similar to Frequency Modulation (FM) PPM- Similar to Phase Modulation (PM) 10.Synchronization Between Transmitter And Receiver PAM- Synchronization between transmitter and receiver is not required. PWM- In this case too no need of any synchronization PPM- In Pulse position modulation synchronization is required. The transmitter sends synchronizing pulses.
