flat frequency response การใช้

• The NS-10 does not have a perfectly flat frequency response.
• Together these allowed a usefully flat frequency response beyond 15 kHz for the first time.
• Their speakers are very well respected by audiophiles who prefer a flat frequency response curve.
• On the other hand, flat frequency response does not necessarily mean a good-sounding amplifier.
• Attenuators have a flat frequency response attenuating all frequencies equally in the band they are intended to operate.
• This is because summing two or more paths with different delays creates a comb filter even when the individual paths have a flat frequency response.
• Thus the combination of channel and equalizer gives a flat frequency response and linear phase F ( f ) C ( f ) = 1.
• Active monitors are typically bi-amped and have an active crossover with custom equalization to tune the monitor to have a flat frequency response.
• If speakers have to be moved very close, care must be taken to ensure they still cover the entire listening area with reasonably flat frequency response.
• Thus, he felt that flat frequency response was both unnecessary and practically impossible to achieve, unlike the vast majority of other speaker designers throughout audio history.
• This permits a loudspeaker to be used with an amplifier having a low internal impedance and a flat frequency response is realized for the combined amplifier / loudspeaker system.
• By comparison, the strain gage type exhibited a flat frequency response above 200 Hz while the piezoelectric type provided a flat response up to 10, 000 Hz.
• Ideally, both filters should be brickwall filters, constant phase delay in the pass-band with constant flat frequency response, and zero response from the Nyquist frequency.
• During playback, the high frequencies must be rescaled to their original, flat frequency response & mdash; known as " equalization " & mdash; as well as being amplified.
• No speaker, monitor or hi-fi sound system, regardless of the design principle or cost, has a completely flat frequency response; all speakers color the sound to some degree.
• At the time, in 1937, these Collins Transmitters were regarded by radio engineers as the  Rolls Royce of broadcasting, with very low distortion and a near perfect flat frequency response.
• Equalization is often unable to achieve flat frequency response at all listening locations in part because of the resonance ( i . e ., standing wave ) patterns at low frequencies in nearly all rooms.
• Graphic equalizers also divide signals into bands logarithmically and report power by octaves; audio engineers put pink noise through a system to test whether it has a flat frequency response in the spectrum of interest.
• Martin Colloms said it possessed an almost perfectly flat frequency response, but that " it neither sounded as lifelike, nor did it really better the musical performance of the standard 3 / 5a ".
• If the impedances and ( or the normalised impedances and ) are pure reactances, then the networks become all-pass, constant-resistance, with a flat frequency response but a variable phase response.
