At any given moment are being bombarded by physical and psychological stimuli computing for one attention. Although our eyes are capable of handling more than 5 millions of data per sec, our brains are capable of interpreting only about 500 bits per sec. with similar disparities between other senses and brain it is easy to see that select visual, auditory or tactile stimuli that we wish to compute at any specific time.
10.physical stimuli usually win the competition for our attention.
A B C
11.the capacity of human brain is sufficient to interpret nearly all the stimuli the senses can register under optimum condition.
A B C
12.eyes are able to hope with greater input of information than ears.

Written Test
The written test consists of three sections based on the MCQ pattern. Each section has 30 questions. There is a choice between Section 2 and Section 3 and only one has to be done.Section 1 is based on basic digital electronics. Section 2 is software orientedSection 3 is advanced digital electronics with questions on setup,hold time,clock violation etc.
Interview
The written test is followed by a lengthy technical interview. The interview may last upto 1 hour or more. It is entirely technical with questions on all basic fundamentals
Profile
