After my 2nd year i started learning matlab from a trainer in my home city ,there i learnt all the basics in matlab that really helped me to explore more about circuits and communication as there are so many tools available in the matlab for different simulation .Image processing ,simulink was the best part in matlab and i really enjoyed while learning matlab . and after completing my third year i did my training in BSNL and DOORDARSHAN Patna .During my training i understand how signals processed and transmitted .It was a really a gud experience
