While is a well-known author for standard engineering textbooks in India (particularly for Power Systems , Network Analysis , and Measurements ), his book "Electronic Devices and Circuits" is not as widely recommended as top-tier authors like Boylestad & Nashelsky , Millman & Halkias , or Sedra & Smith .
Good for last-night revision and university problems , poor for real learning . Use it only if your syllabus specifically lists it. electronic devices and circuits by j.b. gupta e-book
