Electronics and Communication Electromagnetic Field Theory Difficulty: Medium

The Fourier Transform of the signal $$x\left( t \right) = {e^{ - 3{t^2}}}$$ is of the following form, where A and B are constants The ON voltage and forward break over voltage of an SCR depend on the Find, which statement is ""TRUE' for A vector field F I. Solenoidal and irrotational if ∇ ⋅ F = 0 and ∇ × F = 0 II. Solenoidal but not irrotational, if ∇ ⋅ F ≠ 0 and ∇ × F = 0 III. Irrotational but not solenoidal, if ∇ × F ≠ 0 and ∇ ⋅ F ≠ 0 IV. Neither solenoidal nor irrotational, if ∇ ⋅ F ≠ 0 and ∇ × F ≠ 0 For an n-channel MOSFET, if condention parameter (k n ) is 0.249 mA/V 2 , gate to source voltage V GS is 2V IN where V IN = 0.75 V. The current will be Voltage on R, L, C in series circuit are shown below. Value of voltage sources is
