Which of the following is true?

1. A finite signal is always bounded
2. A bounded signal always possesses finite energy
3. A bounded signal is always zero outside the interval [– t₀, t₀] for some t₀
4. A bounded signal is always finite

Correct Option: B

A signal having amplitude within finite boundaries called bounded signal and it can have finite energy or infinite energy. If this signal is power signal, then it possess infinite energy. But in any case, this bounded signal will be finite for all the values of time.
