A logical expression in 3 variables is to be implemented using a multiplexer
i.e; y=/ (A, B, ©). The multiplexer chosen is :

(है) 8:1 Multiplexer (B) 3:1 Multiplexer
[9 4:1 Multiplexer (D) 16 : 1 Multiplexer

An energy signal is one which has :

(A) infinite energy and finite average power
(0) infinite power and finite energy

(C) finite power and zero energy

(D) finite energy and zero average power

A system is said to be stable if :

(^) every bounded input results in a bounded output

(8) superposition applies to that system

(C) the system is time invariant

(0) the output does not begin before the input function applied

The output of LTI system is equal to the :

(A) product of impulse response and input sequence

(8) जणा of impulse response and input sequence

(©) convolution of input and transfer function

(12) convolution of impulse response and input sequence

What is the condition for existence of Fourier transform of a signal x(f) ?
(ಗಿ). 1! signal x(1) is absolutely integrable

(8) If signal x{t) is periodic

(€) If signal x(f) is aperiodic

(D) No such condition exists

11 trigonometric Fourier series of an even function does not have the :
(^) dc term (B) sine term
(0) cosine term (12) odd harmonic terms

A finite duration two sided sequence’s ROC :
(ಗಿ) Entire z plane except z=0 and ‏ودح‎
‎(B) 158 ring (annular region) in the 2 plane
(C) Entire z plane except z=0

(D) Inside a circle centering origin
