What Is Periodic Signal In Data Communication? Signals which repeat itself after a fixed time period are called Periodic Signals. … In data communications, we commonly use periodic analog signals and non-periodic digital signals. ANALOG SIGNAL. An analog signal has infinitely many levels of intensity over a period of time. What is periodic signal? A
What Is Periodic Function In Fourier Series? In mathematics, a Fourier series (/ˈfʊrieɪ, -iər/) is a periodic function composed of harmonically related sinusoids, combined by a weighted summation. … The discrete-time Fourier transform is an example of Fourier series. The process of deriving weights that describe a given function is a form of Fourier analysis.
Where Do We Use Fourier Series? fourier series is broadly used in telecommunications system, for modulation and demodulation of voice signals, also the input,output and calculation of pulse and their sine or cosine graph. What is the Fourier series used for? Basically, fourier series is used to represent a periodic signal in terms of cosine
