Test: Shifting and Time Reversal of Signals - Question 3

Which of these represents amplitude scaling:

Detailed Solution for Test: Shifting and Time Reversal of Signals - Question 3

Amplitude scaling is represented with the equation Y(t) = α X(t)

Test: Shifting and Time Reversal of Signals - Question 4

Y(t) = x(0.5t)

Detailed Solution for Test: Shifting and Time Reversal of Signals - Question 4

When the α value is less than one in time scaling then the signal is said to be expanded or dilated

Test: Shifting and Time Reversal of Signals - Question 5

The operation in which a signal is compressed or dilated by multiplying the time variable by some quantity

Detailed Solution for Test: Shifting and Time Reversal of Signals - Question 5

In time scaling the signal is compressed or expanded by multiplying the time variable

Test: Shifting and Time Reversal of Signals - Question 6

Which of these operations doesn’t affect the amplitude of the signal:

Detailed Solution for Test: Shifting and Time Reversal of Signals - Question 6

In time reversal only the time variable is affected and not the amplitude.

Test: Shifting and Time Reversal of Signals - Question 7

In negative shift time value is:

Detailed Solution for Test: Shifting and Time Reversal of Signals - Question 7

when a finite time value is added to the time variable of the original signal then it is called as negative time shift.

Test: Shifting and Time Reversal of Signals - Question 8

Time scaling is an operation performed on

Detailed Solution for Test: Shifting and Time Reversal of Signals - Question 8

Time scaling is done on independent variables.

Test: Shifting and Time Reversal of Signals - Question 9

How is a linear function described as?

Detailed Solution for Test: Shifting and Time Reversal of Signals - Question 9

The system needs to give a zero output for a zero input so as to conserve the law of additivity, to ensure linearity.

Test: Shifting and Time Reversal of Signals - Question 10

The given mathematical representation belongs to:
y(t) = x(t - T)

Detailed Solution for Test: Shifting and Time Reversal of Signals - Question 10

Time-shifting property: When a signal is shifted in time domain it is said to be delayed or advanced based on whether the signal is shifted to the right or left.
