摘要： In a harmonic adding device, an input/output function part converts a digital sound signal having an input signal level into a digital sound signal having an output signal level determined according to a input/output function and the input signal level. A parameter storage unit stores at least one inflection point. A controller sets the inflection point to the input/output function to enable the input/output function part to add harmonics to the digital sound signal. The input/output function is defined between a positive maximum point and a negative maximum point. The inflection point is set between the positive maximum point and the negative maximum point. The positive maximum point, the inflection point and the negative maximum point are sequentially connected by linear interpolation to formulate the input/output function.

摘要： The quality of music output from audio systems is improved by simulating the effect of low frequency signals in the human ear. This thus allows listeners to perceive the lower frequency signals, even though the speakers may be incapable of providing such low frequency outputs. A method is provided for processing enhancing bass effect in audio signals. The method also results in the bass enhancement being computationally less intensive. The bass effect enhancement techniques are based on the response of sine and cosine transfer functions and on the directional independence of low frequency components. The human ear is unable to resolve directions from low frequency components. The bass effect enhancement technique alternatively is based on the response of an exponential transfer function.

摘要： Audio transducers (headphones, speakers, microphones) inherently do not accurately reproduce the signal presented to them at the input. This can be compensated for by taking into account the transducer characteristics and transforming the input signal using a digital signal processor (DSP) to counteract the inaccuracies. However, for the compensation to take place, the DSP needs to know the characteristics of the transducer. For systems with built-in transducers (like laptops with internal speakers) the characteristics of the internal speakers can be stored on the hard-drive of the laptop and the DSP can read this data and make the appropriate compensations. Because a transducer (headphone, speaker, microphone) has its own characteristics that need to be compensated for separately, a profile is supplied to the DSP either by a database lookup based on an identification made by the user or transducer itself or by profile information stored on the transducer. Once the characteristics of a transducer are known, many additional DSP algorithms can be applied in order to improve the audio performance and even safety of the system.
摘要翻译：音频传感器（耳机，扬声器，麦克风）固有地不准确地再现在输入端呈现给它们的信号。这可以通过考虑换能器特性并使用数字信号处理器（DSP）来变换输入信号来补偿，以抵消不准确性。然而，为了进行补偿，DSP需要知道传感器的特性。对于具有内置传感器（如具有内置扬声器的笔记本电脑）的系统，内部扬声器的特性可以存储在笔记本电脑的硬盘驱动器上，DSP可以读取此数据并进行适当的补偿。因为传感器（耳机，扬声器，麦克风）具有需要单独补偿的自己的特性，所以通过基于由用户或换能器本身做出的标识的数据库查找或通过存储的简档信息将简档提供给DSP 在传感器上。一旦知道传感器的特性，就可以应用许多附加的DSP算法，以便改善系统的音频性能甚至安全性。

摘要： A capacitive amplifier and tone generator detect and amplify an electrical tone conducted by one of a group of wires or a pair of wires in order to identify and trace a particular wire or pair of wires. The capacitive amplifier has a probe for being placed adjacent a wire under test, an input terminal coupled to the conductive probe for receiving an input signal therefrom, a suppression unit coupled to the input terminal for receiving the input signal and for suppressing the noise signals, and an amplifier coupled to the suppression unit to amplify the noiseless output signal. The suppression unit can include an analog/digital converter, a digital/analog converter, a CPU and a memory for suppressing noise frequencies contained in the digital signal values by subtracting from the input signal a time-delayed signal wherein a time-delay period corresponds to a period of the unwanted noise frequency.
