What is the frequency response curve?
To get the most pleasure of their stereo speakers, amplifiers and a microphone, they must accurately reproduce the audio frequency. The manufacturer of your stereo components will often use the frequency response curve to determine the bandwidth and the upper and lower frequency limits of specific components to ensure sound reproduction quality based on visual results of the system response to the frequency input.
The frequency response curve is a visual representation of the quality of amplitude above the frequency generated by specific components. The graph showing such a curve will have a vertical axis and a horizontal axis. The vertical axis is usually marked as a level of sound, also called amplitude, in decibels (DB), while the horizontal axis is marked as frequency, vibration that is captured by the ear and is measured in Hertz (HZ).
The frequency is the number of sound waves that pass through a fixed receptor, such as the ear of the time. This can also be called a cycle. The district response is also a measure represented byFrequency response. It is the determination of how well the circuits of your individual components process constant frequency changes in specific and constantly maintained amplitude.
zone width is a boundary or band that indicates the output of the highest frequency signal to the lowest demonstration of a particular component. fo In the frequency response curve, the top of the curve is recorded where the actual bandwidth is recorded and compared with the proposed component bandwidth. If the actual bandwidth does not have measurements to the design, the frequency response can be improved by a digital or analog filter.
Hi-fidelite amplifier usually has a frequency response of 20 Hz to 20,000 Hz within approximately one dB. Human ear can normally specify sound frequencies included in this specific range, with DB being a volume or amplitude. The system should be able to amplify all frequoresnce in this extent.
specific numbers marked with frequency response curve are not as important as changing the response from frequency response (eg high frequency frequency and vice versa). An acceptable frequency response does not mean accurate sound reproduction, only that the tested component meets the basic requirements for frequency response. This response indicates the tester that the component will accept the input signal and generate the answer. However, the frequency response curve does not define the true sound quality.
