It is the superposition of sinewaves with different amplitudes and frequencies
Sound
The region of frequency where the amplification and delay is reasonably constant i.e. gain is nearly equal to one.
Mid-band frequency
The region where the active circuit may behave as a simple high pass circuit. The response decrease with decreasing frequency and output approaches to zero.
Below mid-band frequency
The circuit behaves like a low-pass circuit and the response decreases with increase in frequency.
Above mid-band frequency
