    for 80) option c is also correct.becoz Q=(1/R)*(L/C)^0.5

    Que no 78, ISRO 2006, I am getting answer as 2A, but in the solution is as 4A. I think there is a mistake in redrawing the circuit. Can you please help?

    Que no 76- ISRO 2006, TO FIND THE GAIN OF THE NETWORK
    I used the formula, 1+Rf/R1 and Rf=100K and R1=1k. My answer would be approximately 40dB. But here it is given as 20dB. Please tell me where I made the mistake

      hello priya g,if gain is 100 then it would be 20db by formula 10log(gain)db its 20log(gain) for current or voltage.

    in q. no. 15 the quantization noise reduces by increasing the sampling frequency but noise density remains the same hence ans ia option A.

    in q.no. 25 that no. is 3753 in octal format and it can be represented in binary with 9 no.of 1s

    in q no. 27 ans should be B bcoz flipflop will half the input frequency of 1 hz and duration would be 2 seconds.
