- Research and Professional Interests:
- My research interests evolve with time and broadly lie at the intersection of three domains: - Signal Processing and Applications, Communication Systems & Networks, and Artificial Intellignece - and learning systems. - - I am also picking up on my long held interest in Signal Processing applications for neuroscience - and recently Electric Circuits (Thanks to my experience at Skylark Wireless) to explore the depths - of my brain. - - Lastly, I am always interested in sustainable technologies, and applied engineering. - - |
Welcome to my Blog!
+Welcome Message
++Hi! After 3 full weekends of efforts, I am successful in creating +a custom blog for myself that renders LaTEX based mathematical +equations. Primarily on this blog I want to share all interesting +things I come across in my preofessional and research career. In +addition, I shall be able to share my opinions, all thanks to +extra time freed from having to maintain my previous wordpress blog. +
+ +MathJax Based Rendering - Love it!
++Want to chekc out how good Math Rendering works on my blog? Check out +the famous Einstein's equation refer as a reference (see below). In +case if anyone is intersted to know, I am using American Mathematical +Society sponsored MathJax +scripts through content delivery network. + +$$ E=MC^{2}$$ + +Lastly, if some finds my blog tmeplate useful, please feel to use +it. As a FOSS supporter, I lay no restrictions on usage, although a +link pointing back to my website/template would be much appreciated. + +

+
+ Last week while working through a problem, I came across + a unique behaviour while working with addition of tones + (these are not harmonics ) with different phase shift. + + To give a brief description, I was adding tones + (exponential – so the signal had both in-phase and + quadrature phase components) – each with different phase + offset. The end goal was to find the change in angle/phase + of product of summation of tones and a reference signal + with respect to reference signal. + + During the experiment, my observations showed that the net + angle/phase deviation from the original was the average of + the phase deviation of the tones being added. Puzzled by + the observations, I resorted to a quick MATLAB simulation + to confirm this. My MATLAB model’s results matched with my + observations. But I am still puzzled about the outcome. + I need to investigate this at some point as this seems to + be a quite interesting problem. + + In this context, I found that in general the following + equation holds true: + + $$ tan^{-1}\lbrace\dfrac{sin \alpha_1 + sin \alpha_2 + \dots } + {cos \alpha_1 + cos \alpha_2 + \dots }\rbrace = \dfrac{\sum_i \alpha_i}{n}$$ +
