Final answer:
In a circuit, replacing capacitors with inductors turns a low-pass filter into a high-pass filter and a high-pass filter into a low-pass filter, due to the inductors' opposite response to frequency changes compared to capacitors.
Step-by-step explanation:
The student is asking about the behavior of electronic filters when capacitors are replaced with inductors. In electronic circuits, a low-pass filter allows low-frequency signals to pass through while blocking high-frequency signals. On the other hand, a high-pass filter does the opposite; it allows high-frequency signals to pass and blocks low-frequency signals. When capacitors are replaced by inductors, the behavior of the circuit changes. Inductors impede the flow of high-frequency signals more than low-frequency ones.
If the capacitors in a circuit are replaced by inductors, a low-pass filter becomes a high-pass filter, and vice versa. This is because inductors resist changes in current, which occurs more rapidly with high-frequency signals, thus acting like a high-frequency filter when placed in a low-pass filter configuration, and as a low-frequency filter when placed in a high-pass filter configuration.
