MY STORY: “Leadership Needs No Title, It Needs Attitude, A Certain Attribute” — Dr Sreeram Srinivasan, CEO, Syrma Technology
The saying ‘Work Hard, Party Harder’ is of special significance to those students who succeed in getting admission to prestigious institutes after years of hard work and sacrifices. They complete their education at top institutes in India and land a good job in a foreign country such as the USA and start enjoying the life of their dreams.
This story is about an individual who graduated from IIT Madras, went on to get his Master’s and PhD degrees from the North Carolina State University in the United States, and landed a job as researcher with two premium research institutions—The Los Alamos National Lab and The Oak Ridge National Labs. But instead of going out on weekends and enjoying life in the States, he spent his time in finding a Vedas’ teacher and learnt to recite the Vedas with all the proper intonations. The individual is today the CEO of Syrma Technology.
Hailing from a famous temple-town in Tamil Nadu and growing up mostly in the North and in Vizag (known as Visakhapatnam today), Sreeram Srinivasan decided to leave the United States and fly back to India in the early 1990s to be with his parents, just when his career was starting to take off in the dream land of the USA. Sreeram got a job with Sundaram Fasteners as senior manager, and everything that happened afterwards never made him want to go back to the States. This is Sreeram’s Story!

Digital Modulation Techniques Simulation Using MATLAB
Different types of modulation techniques are used in telecommunication for transmitting and receiving radio frequency (RF) signals. With MATLAB tools we can analyse the modulation techniques used for these signals along with their mathematical representation. We can analyse carrier frequency parameters like amplitude, phase, and the frequency. Simulation with MATLAB tools helps us obtain the real-world characteristics
