This equation can be used to demonstrate why transmitting highhigh-quality audio across the Internet requires compression. CD audio uses 16-bit stereo sampled at 44,100 Hz. This means 16that one minute of CD audio uses 44,100×16×60×2 = 44,100×16×60× 84,672,000 bits, or slightly over 10 megabytes.

This replaces all bitcodes with unique bitcodes of varying length according to the frequency of the pattern occurrence.4 For instance, the most commonly occurred bit pattern would be encoded as ‘01’, while the next common would be ‘010’ and the next would be ‘011’, and so on.

A standard 56 kbps modem would take 84,672,000/57344 = 1477 seconds or about 25 minutes! 25 minutes is a long time to wait for one minute of audio, so an alternative is imperative. imperative. That alternative was MPEG Audio Layer 3, or MP3.

(bps) of transmitted information in the sense that going to a
higher information rate requires a higher frequency. Thus, the first observation from the frequency line would be that, for optical carriers, which have frequencies in the hundreds of THz, information bandwidth is in some sense free. 信息的带宽在 某种意义上是 免费的 因此在较高的信息率要求较高 的频率这层意义上，要考虑传 输信息的每个bps成本问题

As wavelengths decrease to approach the size of circuit
components, circuit elements are no longer lumped, and leads
can act as reflective components and/or antennas and lumped
电子信息工程专业外文翻译--滤波器
外文原文一、a question for study or discussion1．Research background and purpose1.1 conceptualizeElliptic filter (Elliptic filter), also known as the Call filter (Cauer filter), is in the passband and stopband ripple of a filter. Elliptic filter when compared to other types of filters, in order under the same conditions with minimal fluctuations in the passband and stopband. Same as its wave in passband and stopband, which distinguish it from the Butterworth filter with flat passband and stopband and flat passband and the stopband ripple or resistance with flat, cut than the snow filter passband ripple.A low-pass filter with a frequency response range of the ellipse：Four-order low-pass elliptic filter frequency response。
1.2 scientific researchIn the low-frequency (600Hz=500KHz) commonly used in band-pass filter, large LC filters, poor stability, stability of Crystal filters, but can only be made of narrow-band filter, bad shock and vibration resistance. Active filters are small, but stability and decay characteristics are often poor, and debugging easy. Ceramic filter is poor and low-frequency seismic performance of low temperature coefficient. And than snow filter Butterworth filter transfer function is a polynomial divided by a constant, for the whole network, all zeros in infinite, only infinite stopband attenuation is infinite, and the elliptic filter in both with zeros and poles on the limited frequency. Zero ripple in the passband, that it has a minimum across the passband and stopband ripple, This is distinguished from Butterworth filter with flat passband and stopband。

电子信息工程专业英语教程第三版译者：唐亦林p32In 1945 H. W. Bode presented a system for analyzing the stability of feedback systems by using graphical methods. Until this time, feedback analysis was done by multiplication and division, so calculation of transfer functions was a time consuming and laborious task. Remember, engineers did not have calculators or computers until the '70s. Bode presented a log technique that transformed the intensely mathematical process of calculating a feedback system's stability into graphical analysis that was simple and perceptive. Feedback system design was still complicated, but it no longer was an art dominated by a few electrical engineers kept in a small dark room. Any electrical engineer could use Bode's methods find the stability of a feedback circuit, so the application of feedback to machines began to grow. There really wasn't much call for electronic feedback design until computers and transducers become of age.1945年HW伯德提出了一套系统方法，用图形化方法来分析反馈系统的稳定性。
