Question

Y (t) = x (t/5) is
Compressed signal
ООО
Expanded signal
O Shifted signal
O Amplitude scaled signal by a factor of 5​

Answer 1

Expanded Signal

Step-by-step explanation:

• Whenever transformation are applied on  $y=x(t)$  and then the function becomes $y=x(At)$ and then when $A>1$ then the graph will be compressed otherwise for $A<1$ the graph will be expanded.
• Here in the question A is $1\div 5 =0.2$ which is less than One . So, the graph of the signal Expanded .

• If the signal is of the form $y=x(t-A)$ then the signal will be said to be shifted signal .
• If the signal becomes $y=Ax(t)$ then the amplitude of the signal is scaled and the signal have a change in the amplitude .
• If in this equation the value of A was $2$ then the signal will become compressed signal .
