delta signal 中文意思是什麼
delta signal
解釋
δ信號-
But when sampling rate is high, most traditional digital signal processing and control algorithms are inherently ill - conditioned. considerable progress has been made by the use of delta operator on ameliorating ill - conditioning problems
研究結果表明，當采樣頻率很高時，傳統的信號處理和控制方法存在著不可避免的缺陷，而採用delta運算元描述代替移位運算元描述方法可以適當地改善這些缺陷。 -
Not only can gain mismatch of the sigma - delta modulator be minimized, but the overload of the later stage sigma - delta modulator can also b e resolved without sacrificing the signal noise ratios ( snr ) of the over all system
不僅可以減輕積分三角調變器增益不匹配之困擾，並且可以解決后級積分三角調變器容易過負載之問題；然而，卻不會讓整體系統的訊號雜訊比（ snr ）降低。 -
In the future it may be possible to have such bandpass sigma - delta adcs with userprogrammable digital filter coefficients, so that the passband of a receiver could be modified during operation in response to the characteristics of the signal ( and the interference
未來可能會出現用戶可編程數字濾波系數的帶通- adc ，這樣接收機的通頻帶就可以隨著所接收的信號的特性而改變。 -
Sigma - delta modulator, combined with oversampling, effectively attenuate the in - band quantization noise in the output signal and enhance the signal - to - noise ratio ( snr ) through the shaping of the quantization error
調制器與過采樣相結合，對量化誤差噪聲進行整形，有效衰減輸出信號的帶內量化噪聲，提高了輸出帶內信噪比（ snr ） 。 -
We made an improvement in overcoming the defects in speech signal adaptive delta modulation ( abbr. adm ), such as slope overloading and grain noise. in this method, numerical sliding average filtering was used for filtering decoding speech signal. experiments and analyses indicate that the method makes waveforms in good agreement between the decoding of adm and the original pulse coding modulation ( abbr. pcm ) signal, and considerably improves, the playback speech quality in naturalness, legibility and under standability
針對語音信號自適應增量調制（ adm ）方式中斜率過載和顆粒噪聲缺點，提出了一種改進方法，它利用滑動平均方法對解碼后的信號進行數字濾波.試驗和分析表明，該方法使解碼后的信號波形與原脈沖編碼調制（ pcm ）波形具有很好的一致性，使再生語音質量在自然度、清晰度和可懂度方面比改進前均有較大提高 -
Moreover, using the local nonlinear feedback loop technique of this invention attenuates the voltage signal of the sigma - delta modulator, therefore decreasing the power consumption of the overall sigma - delta modulator system
同時，應用本發明之局部非線性回授?路法亦可以使得積分三角調變器整體系統的電壓訊號衰減，因此可以使得積分三角調變器整體系統的幼率消耗降低。
