This is the first version of my book on “Circuit Theory and Applications” and is intended to be used by the undergraduate students of engineering and computer science. This is one of the foundation books on Solid State Devices.
My inspiration of composing “DSP Laboratories” is my beloved late wife Shahina Maula Rahman . She entered in my life very quietly and remained quite raising my two sons with extreme patience, care and love. She remained as my friend, role model and mentor during my bad and good days for 37 years. She propagated her moral and ethical values that ignited my soul to be able to see and calibrate my mind to achieve my mission as a human being and remained with me with her love and guidance from the eternity. Her dedication in education and services to the community as a good physicist, an excellent teacher, with many other magnificent human qualities as a dedicated mother, a trustworthy wife, and an extremely passionate, warm, soft spoken, and gentle person left a legacy of descendants that will represent her for a long time. I am dedicated to carry on her values in my works through writing books and other humanitarian mission to keep her soul with peace in the eternity. My initial works of composing the books are for the memories of my beloved late wife, Shahina.
Why I am trying to write this book?
Most of the academic institutions from the kindergarten to universities are forced to shut down their on campus activities due to COVID-19 pandemic. Alternatively, in order to continue with the academic classes, most of the higher educational institutions adapted on-line education system through Black Board, Google Classroom or Zoom. Irrespective of their pros and cons at least these are the top Web Conferencing Software that most of the academic institutions are using as an alternative educational platform.
