Frequency-dependent response

Frequency-dependent response refers to how a system reacts differently depending on the rate or speed of the input signal. For example, a musical instrument or electronic device may respond strongly to certain note or sound frequencies but less to others. This behavior occurs because the system's internal components, like resistors, capacitors, or mechanical parts, have properties that vary with the frequency of the input. In essence, the system's ability to process or transmit signals changes with different frequencies, shaping how it behaves or filters the signals it receives.
