Signal Classification Quiz

Identify the property of deterministic signals.

• completely specified by function of time

• partially specified by the function of time

• uncertainty

• partial uncertainty

Choose the condition for a signal to be an energy signal.

• Energy=finite, Power=0

• Energy=infinite, Power=0

• Energy=finite, Power=A (constant)

• Energy=finite, Power=infinite

Identify the operation that can be performed on the unit ramp function so that a unit step function is obtained.

• differentiation

• integration

• multiplication

• double integration

Identify the signal having an amplitude one only at time ‘t’=0.

• Impulse Signal

• Step Signal

• Ramp Signal

• Sinusoidal Signal

Identify the signal having an amplitude equal to one for time t>=0.

• Step Signal

• Ramp Signal

• Impulse Signal

• Sinusoidal Signal

Determine the power of the signal x(t)=10 cos(10*pi*t).

• 50 watt

• 20watt

• 10watt

• 25watt

Examine whether the signal x(t) = 20 sin (200*t) is periodic or non-periodic. If periodic, calculate the fundamental period.

• Periodic, Fundamental Period = 0.01*pi seconds

• Periodic, Fundamental Period = pi seconds

• Periodic, Fundamental Period = 200 seconds

• Non - Periodic

Examine whether the signal x(n) = sin (200*n) is periodic or non-periodic. If periodic, calculate the fundamental period.

• Non-periodic

• Periodic, Fundamental Period = 0.01*pi samples

• Periodic, Fundamental Period = pi samples

• Periodic, Fundamental Period = 200 samples

Examine whether the signal x(n) = 5 cos (0.01*pi*n) is periodic or non-periodic. If periodic, calculate the fundamental period.

• Periodic, Fundamental Period = 200 samples

• Periodic, Fundamental Period = pi samples

• Periodic, Fundamental Period = 0.01*pi samples

• Non - Periodic

Choose the signal that satisfies the condition x(n)=x(-n) for all ‘n’.

• Even

• Odd

• Neither even nor odd

• Energy and Odd
