Как мы знаем, наш сигнал в основном неп कानपुर

Как мы знаем, наш сигнал в основном непрерывный по своей природе, но у нас есть некоторые преимущества дискретного сигнала, потому что мы можем использовать этот дискретный сигнал на цифровом процессоре. Но как мы можем преобразовать непрерывный сигнал в дискретный? Мы можем преобразовать непрерывный сигнал в дискретный, используя процесс дискретизации (в соответствии с критериями Найквиста). У нас есть метод анализа частотной области непрерывного сигнала с помощью непрерывного временного преобразования Фурье (CTFT) и дискретного сигнала с помощью дискретного временного преобразования Фурье (DTFT). Но когда мы преобразуем наш сигнал в дискретный через процесс дискретизации (критерий Найквиста), мы видим здесь наш непериодический, непрерывный сигнал в периодическом обратном сигнале, который будет повторяться в интервале 2π в частотной области. Теперь у нас есть проблема с тем, что наш сигнал в частотной области является непрерывным по своей природе, которая нам не нужна для нашего цифрового процессора, наш сигнал должен быть дискретным по своей природе как в частотной, так и во временной области. Итак, здесь опять же наш сигнал нуждается в процессе сэмплирования, чтобы создать дискретный сигнал в частотной области. Теперь наш сигнал стал дискретным по своей природе в частотной области с процессом дискретизации, поскольку мы знаем, что всегда вычисляем DTFT на единичном круге. Дискретный сигнал в частотной области заставит сигнал повториться на интервалах 2π во временной области. Теперь сигнал будет проанализирован с помощью дискретного преобразования Фурье (DTFT). Но еще одна проблема, связанная с DFT, здесь наш процессор требует много времени на вычисления, поэтому для ее решения мы используем технику FFT.

Let's have a trip to Ganymede.

Ganymede is the largest moon in our solar system. A number of investigations orbiting Jupiter have explored the interimeda more carefully, including four flybys in the 1970s and several passes in the 1990s to 2000s.Pioneer 10 contacted in 1973 and Pioneer 11 in 1974, and they gave information about the satellite. It included more specific determinations on physical characteristics and had facilities up to 400 km (250 mi) on its surface. The closest approach to Pioneer 10 was 44,250,250 km. In 1979, Vyger 1 and Vyger 2 were passing by Ganymede. He refined its size, revealing that it was larger than Saturn's moon Titan, previously thought to be larger.The orbit of Ganymede has a small eccentricity of 0.0013 with an average distance (semi-major axis) of 0.0013,00 km - varying from 1,069,200 km in the peripapis to 1,071,600 km of phypolysis. Ganymede takes seven days and three hours to complete a single revolution. Like most known moons, Ganymede is tidally locked, with one side always facing the planet.Juno is the first mission to directly image this part of Ganymede, the largest moon in the Solar System, larger than the planet Mercury. Ganymede is also the only known moon with its own magnetic field. Scientists have also found evidence of an underground ocean .Ganymede is most uniformly composed of rocky material and water ice. It is estimated that water ice accounts for 46–50% of the Moon's mass.

As we know, our signal is mostly continuous in nature, but we have some advantages of a discrete signal because we can use that discrete signal on a digital processor. But how can we convert a continuous signal to a discrete signal? We can convert a continuous signal to a discrete signal using a sampling process (following Nyquist criteria). We have a technique for analyzing the frequency domain of a continuous signal using the continuous time Fourier transform (CTFT) and for a discrete signal using the discrete time Fourier transform (DTFT). but when we convert our signal to discrete through a sampling process (Nyquist criterion), we see here our non-periodic, continuous signal in a periodic inverse signal that will repeat in the 2π interval in the frequency domain. now we have a problem with our signal in the frequency domain is continuous in nature, which we do not need for our digital processor, our signal must be discrete in nature in both the frequency and the time domain. So, here again our signal needs a sampling process to create a discrete signal in the frequency domain. Now our signal has become discrete in nature in the frequency domain with the sampling process, since we know that we always compute the DTFT on the unit circle. A discrete signal in the frequency domain will make the signal repeat at 2π intervals in the time domain. Now the signal will be analyzed using the discrete Fourier transform (DTFT). But another problem associated with the DFT, here our processor takes a long time to compute. so we use the FFT technique to solve this problem. JATIN KATIYAR.

Social work practice involves the understanding of human development, behavior and the social, economic and cultural institutions and interactions.Hello friend


My name is Aman Kumar

I am student of

SR college of engineering jhansi


Now days, I am doing interns with Hamari pahchan NGO.

I am doing intern for poor people. Those people can't get food. Through thus intern you are learning new thing new value in this world. You will distribute food and other meal to poor, hunger people, then you feel good, donate blood, donate cloth, donate book to children's and my mentor miss Divya tomar mam help us for doing this internship. Help for those people who are poor, helpless, etc

Thanks you
