frequency and response

In ultra high fidelity amplifier design, the amp's frequency response should extend considerably beyond this ( one or more octaves either side ) and might have points < 10 Hz and >.
Professional touring amplifiers often have input and / or output filtering to sharply limit frequency response beyond ; too much of the amplifier's potential output power would otherwise be wasted on infrasonic and ultrasonic frequencies, and the danger of AM radio interference would increase.
Many amplifiers are ultimately slew rate limited ( typically by the impedance of a drive current having to overcome capacitive effects at some point in the circuit ), which sometimes limits the full power bandwidth to frequencies well below the amplifier's small-signal frequency response.
The 3 dB bandwidth of an electronic filter or communication channel is the part of the system's frequency response that lies within 3 dB of the response at its peak, which in the passband filter case is typically at or near its center frequency, and in the lowpass filter is near 0 hertz.

Other bilinear transforms can be used to warp the frequency response of any discrete-time linear system ( for example to approximate the non-linear frequency resolution of the human auditory system ) and are implementable in the discrete domain by replacing a system's unit delays with first order all-pass filters.
The transform preserves stability and maps every point of the frequency response of the continuous-time filter, to a corresponding point in the frequency response of the discrete-time filter, although to a somewhat different frequency, as shown in the Frequency warping section below.
This means that for every feature that one sees in the frequency response of the analog filter, there is a corresponding feature, with identical gain and phase shift, in the frequency response of the digital filter but, perhaps, at a somewhat different frequency.
