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
Save

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

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
Save

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
Save

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
Save

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
Save

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
Save

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.
