If energy of signal f(t) is E then what will be the energy of the signal f(2t)?

1 Rating

Step 1

For any signal *f(t)*, then energy of the signal is defined as

Step 2

Using equation (1), the energy of the signal *f(2t)* will be

Step 3

To simplify equation (2), let’s assume that *k=2t. *Therefore, the following can be ob...
