By Nuno Nogueira, CC BY-SA 2.5, https://commons.wikimedia.org/w/index.php?curid=3912826 MATLAB has been  crucial programming language across worldwide that let us express matrix and array mathematics directly. In signal processing and communication it plays vital role in analysing and exploring time series data in time domain or frequency domain. For analysing non periodic signals in frequency domain we use Fourier transform instead of Fourier series ,which is used to express periodic signals in terms of infinite sum of sinusoidal terms .   Fourier transform can exist for :      1. Energy signals      2. Power signals       3. Impulse signals  That means absolutely integrable signals can have their Fourier transform only.  Formula for Fourier transform;   Then its come to use Fourier transform in MATLAB. So here is the code for Fourier transform of sinusoidal wave , for any other signal we ...

In series of posts celebrating the success of ISRO, this is our third post and in this, we are going to remember a milestone of ISRO's journey, Chandrayaan-1.                                                                                                                      pic by:- Universe today Chandrayaan -1 was India's first mission to the moon. It was launched by ISRO in October 2008 and it was active until August 2009. The mission was a significant uplift to India's space program as most of the technologies used were developed in India. This mission is well known for the discovery of evidence of water molecules on the moon. MISSION HISTORY & OBJECTIVE The word...

         Image credit: NASA/JPL-Caltech The Voyager mission was launched by NASA in Summer of 1977 which consists of two spacecraft named Voyager 1 and Voyager 2. The main mission for the dual spacecraft was to review Jupiter and Saturn. It's been more than 40 years, they have been travelling through our solar system, unveiling the mysteries of outer planets and discovering new moons and now they have reached in interstellar space. Let's have a look on their journey. LAUNCH Voyager 2 was launched on August 20, 1977. After 16 days, on 5th of September, 1977 voyager 1 was launched. The Voyager missions were designed to take advantage of a special alignment of the outer planets that happens every 176 years. It would allow a spacecraft to slingshot from one planet to the next, assisted by the first planet's gravity which means it will require less propellant and time. Voyager 1 was the first man-made object to reach beyond our solar system in interste...

Indian Space Research Organization (ISRO) is the space agency of the government of India. Today each and every person know about ISRO because of its remarkable achievements but since its establishment, it had gone through many ups and downs and many transformations. It started its journey with small rockets of just 30-50 kg payload and now it is carrying 4000 kg of payload to outer space. Let's have a look at its incredible journey. Establishment India's first space organization INCOSPAR (Indian national committee for space research) was established in 1962 by our first prime minister Jawaharlal Nehru and Vikram Sarabhai, a renowned Indian physicist and astronomer. He was the one who initiated space researches in India. Thumba equatorial rocket launching station was set up by INCOSPAR in Thiruvananthapuram for upper atmospheric research.  On 15th of August 1969, INCOSPAR was dissolved and ISRO was established with the vision of  "harnessing space technology f...
