GATE EC 2017 Question Paper (05-Feb-2017) (Shift 2)

A connection is made consisting of resistance A in series with a parallel combination of resistances B and C. Three resistors of value 10 Ω, 5 Ω, 2 Ω, are provided. Consider all possible permutations of the given resistors into the positions A, B, C, and identify the configurations with maximum possible overall resistance, and also the ones with minimum possible overall resistance. The ratio of maximum to minimum values of the resistances (up to second decimal place) is __________.

An LTI system with unit sample response h[n] = 5δ[n] - 7δ [n - 1] + 7δ [n - 3] - 5δ [n - 4] is a

The input x(t) and the output y(t) of a continuous-time system are related as:

$y\left(t\right)=\underset{t-T}{\overset{t}{\int }}x\left(u\right)du$

The system is:

An n-channel enhancement mode MOSFET is biased at V${}_{GS}$ > V${}_{TH}$ and V${}_{DS}$ > (V${}_{GS}$ - V${}_{TH}$), where V${}_{GS}$ is the gate-to-source voltage, V${}_{DS}$ is the drain-to-source voltage and V${}_{TH}$ is the threshold voltage. Considering channel length modulation effect to be significant, the MOSFET behaves as a

An npn BJT is operating in the active region. If the reverse bias across the base-collector junction is increased, then
