Amplitude modulation

As we approach the summer of 2016, the issue of immigration in the Western world has yet to lose momentum; whether Donald Trump is arguing to build a wall on the Mexican border in the U.S. or European parties against immigration are gaining traction, it’s become clear that opposition to multiculturalism is currently rampant. German chancellor Angela Merkel is under fire for the number of refugees being let into this country; but perhaps her actions are serving one of her oldest goals, true…

Is the radio still one of the major devices? And what did the invention of the radio make possible for us? Radio made the communication over distance faster, it brought entertainment to the people’s houses, cars and it made live sessions possible. We have to ask ourselves what the radio waves might do to our body. Radio waves are made of two type’s, electrical and magnetic energy. (Steve Parker, “How Radio Works”) Nobody knew how it will affect the human body. They are largely unaffected by day…

The emergence of modern media technologies has revolutionized the way humans conduct their daily lives. The evolution of media technology has and will continue to impact the information we consume, how we consume it and how that content is created. Being and individual born in the 90s, I have witnessed massive innovation take place on a global scale that has impacted the media technologies I use. As a toddler, much of the media entertainment I was exposed to was derived from clunky TV’s,…

Porter’s Five Forces Model of Competition The five forces analysis addresses industry factors affecting competition within the areas of rivalry, barriers to entry, bargaining powers of suppliers and buyers, and the threat of substitutes. For SiriusXM to remain competitive within the radio broadcast industry, they must carefully monitor and address each of these forces. Rivalry Intensity – (Strong). Rivalry within the radio broadcast industry is a strong force, as many options are available to…

Due to different media forms, New Zealand has experienced numerous transformations over time. There is a range of different media forms such as television and print media, however radio is an important one to be discussed, along with the negative impacts it has brought through the transformations. The transformations include deregulation, privatization and commercialization. It is important to consider how these transformations have then in turn negatively affected the media’s ability to…

the three-level inverters often need to operate with modulation indices (m) lower than 0.5 [6]- [10]. Additionally, at lower modulation indices, traction drives operating with induction motors (IMs), interior permanent magnet motors (IPMs) or synchronous reluctance motors (SynRMs) may need to provide higher reactive power, thus operating with a lower power factor (pf) [9], [11]- [17]. For example, in [9], the power factor of IPMSMs at 0.2 modulation index is shown to be 0.52. The power factor of…

15. What is modulation? Give its advantages. Answer Definition of Modulation The message signal having weak strength cannot be transmitted directly through the communication channel Since carrier signal carries the message signal therefore, certain carrier signal parameters are changed according to the message signal. A method in which message signal is transmitted to the receiver with the help of carrier signal is called modulation. In this, both carrier signal and message signal are combined…

Orsolya szalárdy et al, 2013 stated that the primary cue for the stream segregation lies in the difference in amplitude modulation which further interacts with other primary cues such as frequency and location difference. Separation in the AM frequency is used as a cue in the segregation of auditory stream. As the separation in the amplitude modulation increased, the duration of segregate perceptual phases increased, thereby decreasing the duration of integrated phases. A study…

Acceleration and deceleration, obstacle negotiation, disturbance rejection and turning are all examples of behavior that require modulation of walking speed which is in turn driven by transient changes in muscle activations. A few studies in recent years have explored characteristics of transient walking [1], [2], [3]. It has been suggested that control of speed works through modulation of braking and propulsive impulses and to increase speed subjects change the braking impulse more than the…

used, as shown in Fig. 7. The proposed approach was tested on a system which operates at a nominal switching frequency of 6 kHz at the linear modulation index range and with 12 kHz at the over-modulation index range. The DC-link voltage…
