For the signal u(t) , Energy(E) & Power (P) is

• 
  E=0, P=1

• E=∞, P=1/2

• E=1/2, P=∞

• E=1, P=0

Which of the following impulse response h(n) represents a stable LTI system

• Both A & C

Fourier transform of 1 is =

Fourier transform of u(t) is

• π δ(w)+(1/w)

• π δ( w)+(1/jw)

• 1/jw

• π δ( w)

The Fourier transform of x(-t) is

• -X(jw)

• X(jw)

• X(-jw)

• X(1/jw)

Gibbs phenomenon occurs , because of

• Abruptly terminating the signals

• Abruptly integrating the signals

• x(t) should be continuous only 

• Above all

A linear system satisfies the principle of

• additivity

• additivity & homogeneity

• homogeneity

• stability

The convolution δ(t) * u(t) is

• 1

• u(t)

• δ(t) u(t)

• δ(t)
