If an electronic frequency falls outside of a circuit's bandwidth, that frequency will be _____.

1. sent to another circuit

2. saved

3. corrupt

4. lost

The correct answer is: lost

When an electronic frequency falls outside of a circuit's bandwidth, that frequency is effectively lost because the circuit is designed to operate only within certain frequency limits. Bandwidth defines the range of frequencies that a circuit can effectively process. Any signal that falls outside of this range cannot be captured, amplified, or transmitted by the circuit. In practical terms, if a frequency is outside the bandwidth, it means that the circuit's components (such as filters, amplifiers, and transceivers) are not capable of detecting or responding to those external frequencies. This results in the loss of that frequency's information. The other choices do not accurately depict the situation: frequencies aren’t sent to another circuit or saved, nor do they become corrupted; they simply do not exist in the output of the circuit.
