The binary signal when ASK is modulated, gives a zero value for LOW input and gives the carrier output for HIGH input.
The amplitude of the resultant output depends upon the input data whether it should be a zero level or a variation of positive and negative, depending upon the carrier frequency.Īmplitude Shift Keying (ASK) is a type of Amplitude Modulation which represents the binary data in the form of variations in the amplitude of a signal.įollowing is the diagram for ASK modulated waveform along with its input.Īny modulated signal has a high frequency carrier.
In this chapter, we will be discussing the most prominent digital modulation techniques. There are many types of digital modulation techniques and we can even use a combination of these techniques as well. Hence, digital modulation techniques have a greater demand, for their capacity to convey larger amounts of data than analog ones. In addition, the performed analysis could easily be applied and operationally compared in other different heritage environments.Digital Modulation provides more information capacity, high data security, quicker system availability with great quality communication. The results provide a fresh look at the technological changes embodied by new uses in old industrialization sites. The results are valuable because they offer an original profile of selected industrial heritage sites, characterized by an important connection between visitors, visited spaces, and available resources the interaction of these three elements with the surrounding territory, fostering a new competitive capacity the projection of each place in a modern and attractive way and the commitment to an efficient and sustainable local management model. It includes an extensive bibliographic review and analyzes different variables linked to webpages, which are the main source of information for visitors, and studies the level of digitization using a survey of the technical managers. The study answers questions about the level of digital transformation of certain preselected buildings and areas of great historical and technical interest. This research represents a novel contribution regarding the application of digital technology to the management and cultural promotion of industrial heritage.
