3. Great work sir...

4. sir,
is the answer of Q no.74 of 2009 right?

1. 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....

2. excellent

5. please can you provide for CS also

6. can anybody solve Q no: 55 of 2006.actually i m getting answer as -30 DB
but the answer given is 0 DB...

7. gain(db)=10 log(Po/Pi);-->P in watts
30=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....

1. This comment has been removed by the author.

2. po=10^-3
=>10log(10)^-3
=> -30log10
=>-30DBm (as log10 to base 10 is 1)

3. you convert watt to dbwatt..
watt to dbm conversion is,
P=(10log P)+30=0 dbm.
P0=1 milliwatts= -30 dbw=0 dbm...

4. P(dbm)=10log(x/1mw)
here x=1mw
so P(dbm)=10log(1mw/1mw)=10log(1)=0 dbm

8. 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.

9. 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..

10. Thanks sir !!!!!
