If energy of signal f(t) is E then what will be the energy of the signal f(2t)?
For any signal f(t), then energy of the signal is defined as
E- t
Using equation (1), the energy of the signal f(2t) will be
E, (2) d ->(2)
To simplify equation (2), let’s assume that k=2t. Therefore, the following can be ob...
