Such a system is (a) non-causal system x(t) (b) stable system (c) causal system t=T t (d) unstable system 1.2 In a series RLC high Q circuit, the current peaks at a frequency (a) equal to the resonant frequency (b) greater than the resonant frequency (c) less than the resonant frequency (d) none of the above 1.3 The voltage across an impedance in a network is V ( s ) = z ( s ) I ( s ) , where V(s) , Z(s) are the Laplace transforms of v ( t ) , z ( t ) and i ( t ) . The voltage v ( t ) is: the corresponding time function 1 (a) ( t ) = z ( t ) . (t ) (b) ( t ) = i (t ) .z ( t ) d 0 1 (c) ( t ) = i (t ) .z (t + ) d (d) ( t ) = z ( t ) + i ( t ) 0 1.4 Two two-port networks are connected in cascade. The combination is to be represented as a single two-port network. The parameters of the network are obtained by multiplying the individual (a) z-parameter matrix (c) y-parameter matrix 1.5 (b) h-parameter matrix (d) ABCD parameter matrix The pole-zero pattern of a certain filter is shown in the figure below. The filter jw must be of the following type. (a) low pass (c) all pass (d) band pass +j2 (b) high pass +j1 -1 +1 -j1 -j2
