i am a normal engg college student text books never invited me....but this lecture is awesome nw i started studyng inyoutube only thanks for this nptel programme.....really damn helpful
A sine wave voltage wave form is displayed, with the X axis represents time and Y axis the amplitude. An amplifier just amplifies the signal amplitude ( y axis) only. In one figure ( second slide), It is displayed that the output wave as a magnified sine wave. ( I mean that the time and voltage is expanded). A student may assume that the out put of an amplifier will not only increase the amplitude, but also changes the frequency of the signal.
You are my teacher Sir. I learned nothing from my school and now I am watching your lectures to do my course work. You are my teacher. I honour you and accept you as my teacher. Thank you Sir.
His video lessons are useless and cheating. Nothing is working. When we click only long time takes and simply a LAMP with IIT MADRAS images is shown. No further progress. These stuffs may please be removed from this site
Really good and simple explanation easy to understand.
Very useful.
Thanks Prof.
