Here I am giving you interview question for candidates of electronic and communication engineering for recruitment in Indian space research organization

ISRO interview questions :

In radar we may know how a CW radar works and what are its applications.

. In digital we know how to reduce a Boolean expression using K-map. But do you know difference between looping 1s and 0s in K-map?

Do you know there is a limitation in Kmap?

Do you know any other method to reduce the expressions? Is there any limitation for that?

In mechanical we have heard a lot about 100cc or 150 cc bikes. What actually cc here means?

Is there any relationship with that with performance if so how and why?

Is there any 100% efficient Carnot cycle? Why?

In electrical we have heard a lot about transmission loss why it is caused? Can we prevent it ?

In Computer you know methods of sorting? Which is the most efficient and why?

In Physics do you know what is the cause of hall effect?

Sampling theorem, aliasing effects, digital modulation (compare BPSK and BFSK), what is FFSK?, line coding (compare Manchester and NRZ scheme), turbo codes??, trellis coded modulation??, advantage of cyclic codes

Eqvt ckt of transmission line and explain all the primary and secondary constants?

- losses associated with transmission line

- antenna gain, isotropic antenna?, antenna applns at different freq

- microwave sources - klystron, magnetron etc.
