yes that is correct try solving from last resistors,since last 2 are in series so voltage drop will be same.2V,now remove those two resistor with 2V and go on moving towars the source in the same manner,u will get the answer....

sir question no 57 of 2013,why u have not considered the negative frequencies in the spectrum diagram.AS PER MY SOLUTION THERE WILL BE TOTAL 5 DELTA FUNCTION i.e at 0HZ,+/-1MHZ AND +/-3MHZ..PLZ REPLY SOON.

sir QNO 44 OF 2009 HOW DID U CONCLUDE THAT 25-J50 IS WRONGLY MARKED WHY IT CAN'T BE 50+J50 BECAUSE BOTH ARE ON THE SAME CONSTANT RESISTANCE CIRCLE. SO THE RESISTANCE SHOULD BE SAME BUT I M NOT GETTING ANY CLEAR INDICATION OF REACTANCE CIRCLE TO CONCLUDE THE ANSWER..

Hello sir, My branch is instrumentation. Can you please tell me that question papers of instrumentation and electronics same or different? Thanks in advance

find equivalent resistance: 60+7||R total currant= 50/(Requivlt) current through R= total I *( 7/(7+R)) (main current*(resistance of other branch/sum of resistances) =4 Ampere solve it to get R=3.5

Can u tell the solution of Q.58 of 2006 paper and also confirm the answer for Q.50 of 2006..because BCH codes are a type of cyclic codes so Ans. shoulb be D

In 2009,4th question,I think the largest mod value is 16 ie,Using the formula,f=1/(2ntpd) on putting the given data data,the value of n is approx 4.For 4 bits the largest value is 16(ie,0-15). Pls check my calc and reply fast,feel free to tell if its wrong..

ReplyDeletesir,

ReplyDeleteis the answer of Q no.74 of 2009 right?

yes that is correct try solving from last resistors,since last 2 are in series so voltage drop will be same.2V,now remove those two resistor with 2V and go on moving towars the source in the same manner,u will get the answer....

Deleteexcellent

Deleteplease can you provide for CS also

ReplyDeletecan anybody solve Q no: 55 of 2006.actually i m getting answer as -30 DB

ReplyDeletebut the answer given is 0 DB...

gain(db)=10 log(Po/Pi);-->P in watts

ReplyDelete30=10 log(Po/(1*10^-6));-->Pi=1 micro wats

Po/(1*(10^-6))=10^3;

Po=10^-3 watts=0dbm........so ans is 0 dbm....

This comment has been removed by the author.

Deletepo=10^-3

Delete=>10log(10)^-3

=> -30log10

=>-30DBm (as log10 to base 10 is 1)

you convert watt to dbwatt..

Deletewatt to dbm conversion is,

P=(10log P)+30=0 dbm.

P0=1 milliwatts= -30 dbw=0 dbm...

P(dbm)=10log(x/1mw)

Deletehere x=1mw

so P(dbm)=10log(1mw/1mw)=10log(1)=0 dbm

sir question no 57 of 2013,why u have not considered the negative frequencies in the spectrum diagram.AS PER MY SOLUTION THERE WILL BE TOTAL 5 DELTA FUNCTION i.e at 0HZ,+/-1MHZ AND +/-3MHZ..PLZ REPLY SOON.
