EE paper now a days requires covering of almost entire syllabus. The approach is to read from the textbooks and practice their solved examples and previous year papers of IES(both E&T and EE) and CSE. Also most of the topics are not covered by the single book. I have also given the reference sources. Stick to the syllabus for all the topics.
1. Circuit Theory: A. Chakrabarti(Dhanpat Rai)
2. Signals and systems: Oppenheim and Willsky. For DFT/FFT, refer to Oppenheim’s book on DSP. For better coverage of z-transform, refer any Indian author.(I had Sanjay Sharma’s book)
3. E.M. Theory: K.D. Prasad. For Smith chart and other minor topics left refer Jordan & Balmain.
4. Analog Electronics: J.B. Gupta. For topics like feedback amplifiers and any other topics not covered well in that book refer Sedra & Smith.
5. Digital Electronics: M.Morris Mano
6. Energy Conversion: Ashfaq Hussain. For topics not covered in detail refer Fitzgerald.
7. Power Electronics and Electric Drives: PS Bhimbra
8. Analog Communication: (a) Simon Haykin (b) BP Lathi (c) Singh and Sapre(TMH)
1. Control Systems: Nagrath & Gopal
2. Microprocessors and Microcomputers: RS Gaonkar
3. Measurement and Instrumentation: AK Sawhney
4. Power Systems: (a) Nagrath and Kothari (b) CL Wadhwa
5. Power System Protection: (a) CL Wadhwa(only chapters of psp, circuit breaker) (b) Badriram &Vishwakarma
6. Digital Communication: Same as Analog Communication. For Data Networks and 7-layered architecture I referred Forouzan(TMH).
