Modulation is a term widely used in telecommunication or wireless networks. Modulation basically is used to convert information (digital bit stream or analog audio signal) in the form that can be physically transmitted over the air or cable. Information is referred as baseband or modulating signal....
However as there now are more efficient and convenient methods of modulating a signal, its use is declining, although it will still be very many years before it is no longer used.Many of the more efficient methods of modulating signals are based around AM: single sideband and quadrature ...
Modulation in physics isthe process of changing one or more properties of a periodic waveform, the carrier signal, with a modulating signal that typically contains information that is to be transmitted from one place to another. There are three types of modulation namely: Frequency modulation. Wha...
Modulation is the process of transmission of information such as images or videos on an electrical signal. Demodulation is defined as the process of extracting this information. Know what is modulation in detail.
Basically, what the modem does is take the digital signal from the computer and add it on top of an analog telephone signal (i.e., modulates it) so that it can be transferred through the telephone line. Since your modem sends information through a telephone line by modulating digital signa...
A: 5G is based onOFDM(Orthogonal frequency-division multiplexing), a method of modulating a digital signal across several different channels to reduce interference. 5G uses5G NRair interface alongside OFDM principles. 5G also uses wider bandwidth technologies such as sub-6 GHz and mmWave. ...
Carrier Signal Generation The process begins with the generation of a carrier signal, typically a sinusoidal waveform at a specific frequency. This carrier signal is then split into the in-phase (I) component and the quadrature (Q) component. These components are orthogonal, meaning they are phas...

In individuals who know more than one language, the languages are always active to some degree. This has consequences for language processing, but bilinguals rarely make mistakes in language selection. A prevailing explanation is that bilingualism is supported by strong cognitive control abilities, deve...
