What is Pulse Position Modulation ?
Pulse position modulation is a modulation technique in which the position of pulse varies according to instantaneous value of amplitude of sampled modulating signal. If we try to summarize it,
Displacement of pulse is directly proportional to amplitude value of sampled message signal.
The basic picture in this modulation is that with increase in amplitude of signal, the position of pulse shifts according to some reference. It is important to note that the width of pulses remains constant only there position changes. Hence transmitted power remains same.,
Pulse Position Modulation (PPM)
Pulse Position Modulation is another kind of important modulation technique used in electronics communication system apart from amplitude and phase modulation. In this article, we will discuss what is pulse position modulation, we will understand its block-diagram and how do we detect pulse position modulation. Later we will understand the working of pulse position modulation through its circuit diagram. We will discuss the advantages, disadvantages and applications of this modulation technique. In the end, we will conclude the article.
