What does the term "sampling theorem" imply in DSP?

A) Signals must be continuous

B) Signals can be reconstructed from their samples if sampled correctly

C) Analog signals cannot be sampled

D) Only low-frequency signals can be sampled

Answer: B) Signals can be reconstructed from their samples if sampled correctly

Explanation: The sampling theorem states that if a signal is sampled at a rate greater than twice its highest frequency, it can be completely reconstructed from those samples without losing information.
