Pulse Time Modulation

The present study is conducted in order to cast light on the discussion regarding the definition of pulse time modulation. The explanation of the pulse width will be included in this particular section of the discussion in order to represent in-depth knowledge about pulse time modulation. In addition, the classification of the pulse time modulation will be included in the study for a better understanding of the pulse amplitude and pulse position modulation. In relation to expressing facts about the modulation of pulse time, the advantages and disadvantages are stated in the current study as well. 

Definition of Pulse Time Modulation 

In a general viewpoint, pulse time modulation can be demonstrated as the process of involving the sampling and the pulse train on the axis of the time of a signal. In a more simple diction, it can be demonstrated as the modulation scheme or technique of the intervals of time that lies between the success pulse of the amplitude that is constant and the duration of the pulse. In a briefer manner, pulse time modulation can be described as the combination of pulse position modulation and pulse width modulation. 

Explanation of Pulse Width

The measurement of the time that is elapsed and lies between the trailing and leading edges of a single pulse of energy is called the pulse width. The measurement of the elapsed time has been conducted with the usage of electrical signals. This pulse width has been primarily used in the field of power supplies and radar. For an idling engine that can be operated at a normal temperature, the typical injector pulse width will be from 2.5 to 3.5ms.

Types of the Pulse Time Modulation

Pulse time modulation can be classified on the basis of two distinct categories of modulation that are mentioned in the below section:

• Pulse width modulation is a basic scheme that helps in reducing the average power that can be delivered by an electrical signal. 
• On the other hand, pulse position modulation refers to a scheme of analog modulation where the width and the amplitude of the pulse have been kept in a constant manner

Pulse Width Modulation and Pulse Position Modulation- An Overview

The modulation of the pulse position has been conducted based on the modulated signals and the width of the pulse. On the contrary, the modulation of the pulse width has been used in a communication system in order to encode the amplitude of a signal. In the case of the modulation of the pulse width, the amplitude of the signal has been encoded right into the duration of the analog signal. This analog signal usually is usually referred to as the carrier signal, the particular signal on which the transformation depends.  

Pulse Time Modulation-Disadvantages

In comparison to the pulse-amplitude modulation, the pulse time modulation requires larger bandwidth. The main reason behind this is the dependency on both the pulse width and amplitude. Therefore, it can be stated that this condition is recognised as one of the primary disadvantages of the modulation of pulse time. As the pulse width modulation has a short switching time, sometimes voltage spikes occur in the pulse time modulation. This particular phenomenon has been considered the disadvantage of the modulation of pulse time.   

Advantages of Pulse Time Modulation 

It has been seen that the modulation of pulse time shares a close relationship with the pulse width modulation scheme. Following this particular fact, the low power consumption of the pulse width modulation has been considered an advantage of the modulation of pulse time. In addition, the pulse time modulation has less noise interference along with allowing the easy detection of noise. On the other hand, the scheme eliminates the requirement of the synchronizer between the receiver and the transmitter. The power efficiency of the pulse position modulation is the highest in comparison to the other types of modulations of pulses. This particular scenario is considered an advantage of the PTM. 

Conclusion 

It has been stated in the above section of this study that the definition of the modulation of pulsed time refers to the modulation techniques of the intervals of time between the pulse of constant duration and amplitude. The regulation of the width of the pulses that have been referred to as the pulse width modulation has been discussed in the discussion section of the study. Along with that, the modulation of the pulse width, a discussion based on the pulse position amplitude has been included in this study as well.
