- A bulb in a staircase has two switches, one switch being at the ground floor and the other one at the first floor. The bulb can be turned ON and also can be turned OFF by any one of the switches irrespective of the state of the other switch. The logic of switching of the bulb resembles

Consider a vector field
. The closed loop line integral 
can be expressed as - Two systems with impulse responses h1 (t) and h2 (t) are connected in cascade. Then the overall impulse response of the cascaded system is given by
- In a forward biased pn junction diode, the sequence of events that best describes the mechanism of current flow is
- In IC technology, dry oxidation (using dry oxygen) as compared to wet oxidation (using steam or water vapor) produces
- The maximum value of θ until which the approximation sinθ ≈ θ holds to within 10% error is
- The impulse response of a system is h(t) = t u(t) . For an input u(t -1) , the output is

The Bode plot of a transfer function G(s) is shown in the figure below.
The gain (20 log |G(s)| ) is 32 dB and -8 dB at 1 rad/s and 10 rad/s respectively. The phase is negative for all ω. Then G(s) is -
In the circuit shown below what is the output voltage (Vout) if a silicon transistor Q and an ideal op-amp are used?
-
Consider a delta connection of resistors and its equivalent star connection as shown below. If all elements of the delta connection are scaled by a factor k, k> 0, the elements of the corresponding star equivalent will be scaled by a factor of
