Modulation Pdf Pdf Modulation and demodulation introduction a communication system that sends information between two locations consists of a transmitter, channel, and receiver as illustrated in figure 1. the channel refers to the physical medium carrying the information signal (voice, video, data etc.) from one location to another. 02 modulation free download as pdf file (.pdf) or read online for free.
Modulation Pdf Modulation Frequency Modulation Module 12, modulation principles, discusses the principles of modulation. module 13, introduction to number systems and logic circuits, presents the fundamental concepts of number systems, boolean algebra, and logic circuits, all of which pertain to digital computers. Frequency modulation introduction as in chapter 1, the need for modulation arises because the range of frequencies contained in a baseband signal is not, in general, the same as the range of frequencies which can be transmitted by the communications channel. am – amplitude modulation medium wave (300 khz to 3 mhz), short wave (3–30 mhz). Classification of modulation the process of modulation can be classified according to the type of message signal or modulating signal used along with the type of carrier signal used. 1.1 modulation modulation is the process of changing the characteristics (amplitude , frequency , phase) of carrier signal according to the instantaneous value of modulating signal. message signal is a low frequency signal (voice 0 4 khz and video 0 6 mhz)⇨ it cannot be transmitted to a long distance.
