Let a uniform surface charge density of 5 nC/m? be present at the z=0 plane, uniform line
charge density of 8 nC/m be located at x=0,z=4 and a point charge of 2 4C be present at

P(2,0,0). If ¥ =0 at A(0,0,5) the V at B(1, 2, 3) is : (Write your answer in Volts)

Twenty-four voice signals are sampled uniformly at a rate of 8 kHz and then time-division
multiplexed. The sampling process uses flat-top samples with 1 ಟೂ duration. The multiplexing
operating includes provision for synchronization by adding an extra pulse of 1 us duration. The
spacing between successive pulses of the multiplexed signal is (Give the answer in ng) :

(ക) 2000 (18) 3000
(0) 4000 (D) 1000

Norton's theorem states that a complex network connected to a load can be replaced with an
equivalent impedance :

(ക in series with a current source
(B) in parallel with a voltage source
(C) in series with a voltage source

(D) in parallel with a current source

Tn the circuit give below, If the “on” resistance of the MOSFET labeled “Q,"is 200 Q and the

“on” resistance of the MOSFET labeled “@, " is 100 ഒ, then if 10 mA of current is sourced in
the high state, V,, is X. If 10 mA of current is sunk in the low state, ட 18 Y, then X +Y=?
