Editorial column

Dear Students,

Vasant Panchami As Diwali is the festival of light to worship Ma Lakshmi, Navratri is the festival of dandiya to worship Ma Durga, Vasant Panchami is the festival of knowledge and arts to worship Ma Saraswati. It is celebrated as the birthday of Goddess Saraswati.

Vasant means start of spring season. It is felt in the air, new leaves and blossoms appear in the trees. Season undergoes change with the promise of new life and hope. It also indicates the festival of colours- Holi.

It is believed that it is the auspicious day to begin pre-school children’s foundation of education. This edition is devoted to the Goddess of Education “Ma Saraswati”. ' Pranam Mantra'

Om Saraswati Mahabhagey, Vidye Kamala Lochaney | Viswarupey Vishalakshmi, Vidyam Dehi Namohastutey || Jaya Jaya Devi, Charachara Sharey, Kuchayuga Shobhita, Mukta Haarey | Vina Ranjita, Pustaka Hastey, Bhagavati Bharati Devi Namohastutey ||

Staff Corner Digitally Implemented Modulator

- Prof. Kavita Monpara (Lecturer, EC Dept.) In the satellite communication, as we know that power and bandwidth are most important parameter. For both the parameters one of the modulation technique QPSK modulations is used in satellite communication. In digital modulator, there are mixer, 90 degree phase shifter, adder, local oscillator devices are used. All they are analog devices. So there are some limitations like

aging, Frequency sensitiveness, temperature sensitiveness are present due to these analog components. In on board processing system, these limitations degrade the performance of this modulator. As we know that for satellite communication miniaturization of circuit is very important. So the new approach in satellite communication eliminates all the limitations which are facing due to presence of analog components. For on board processing system of satellite if we use digital component instead of the analog components than all these limitations can be removed. For satellite communication the circuit is develop for particular specifications. If we use digital devices, we can get variable data rate of modulation. We can develop the circuit in which carrier is generated digitally. There is a great emphasis on the minimization of hardware and less power consumption in SATCOM. The new approach minimizes the component count and hence reduces the PCB size. In this approach summation, orthogonal sub carrier generation and mixing of sub carrier with data rate are all digitally implemented inside the FPGA. Earlier each of this function was being implemented by external

analog components. So the components count was more leading to bigger PCB size. It is also cost effective. So this new approach is very useful in SATCOM. And after some time, it will launch for future satellite mission. The block diagram shows QPSK modulator for new approach with comparison to the general QPSK mode.

*Someday* *Someday I might be there, * *Someday we'll be together....* *Just like the rain waits for the call,* *And to its mother earth she would fall.* *Cold hours play by,* *I still stay warm upon the sky...* *For you... For you...* *Like the wings of mother protect the baby's cry...* *I decorate in sweat,* *The oceans, beaches, trees and grasses wet,* *For your feet shall touch it one day;* *And your life will then be all beautiful nights, no sun to set. * *But you're still far away,* *Don't know, I'll be able to cross the way;* *But I keep walking... to you,* *May be someday I'll find you too...* *Among the heavy trees, and high grass,* *I still try to catch a sight of you as I pass,* *Like a shepherd I play the tune, though not with the flute,* *In a hope u shall return as a lost sheep to its mass.* *O! My snake, return to your master, * *For I'll play the music for you to dance till I die, * *O! My flower, come back to shine,* *For I'll never ever allow the sun to fare good-bye.* *Thus I keep walking on this very path,* *And gather all the thorns and wounds;* *For I know one day, we'll walk this path back together,* *With no pain, no wounds and no sorrow.....*

Param Pujaniya Guruji (February 19, 1906 – June 5, 1973),

Madhav Sadashiv Golwalkar popularly known as Param Pujaniya Guruji , was the second "Sarsanghchalak" (Supreme Chief) of the Rashtriya Swayamsevak Sangh and was a famous Hindu Nationalist leader of India. His urge towards spiritual salvation takes him to Sargachi in Bengal State. He takes DEEKSHA from Swami Akhandanandji of Ramkrishna Math & returns to Nagpur following samadhi of Swami Akhandanandji. He translates speeches of Swami Vivekananda delivered at 1893 Chicago Religious Conference. Also wrote "WE OR OUR NATIONHOOD DEFINED" in three days.

He was a great scholar, wide and well read. He could talk on any subject with effective participation.

He was a man with vision - a person who could look into the future and prepare his followers.

He united various Sants and Sadhus on the platform of Vishwa Hindu Parishad which since 1964 has blossomed into a worldwide organization.

He always shunned publicity in spite of his personal magnificent work and achievements. He worked and sacrificed for the good of the Society without desiring publicity-It was his path of life.
