The gain signal used in dynamic range control is processed on a dB scale for all dynamic range controllers. There is no reference for the dB output; it is a straight conversion:xdB=20log10(x). You might need to
动态范围控制(Dynamic Range Control,DRC)将输入音频信号的动态范围映射到指定的动态范围,可以使声音听起来更柔和或更大声,即一种信号幅度调节方式。通常映射后的动态范围小于映射前的动态范围,因此称之为动态范围压缩。音频信号可以进行整体的动态范围控制,也可以划分为若干子带分别进行动态范围控制。DRC广泛应用于音频信...
Compare the effect of dynamic range limiters and compressors on a drum track. Create a dsp.AudioFileReader System object and a audioDeviceWriter System object to read audio from a file and write to your audio output device. To emphasize the effect of dynamic range control, set the operational...

dRG = noiseGate creates a System object, dRG, that performs dynamic range gating independently across each input channel. dRG = noiseGate(thresholdValue) sets the Threshold property to thresholdValue. dRG = noiseGate(___,Name,Value) sets each property Name to the specified Value. Unspecified pr...
同样，增加预测步长$Np$也引发了控制效果的下降，这与历史输入窗口变短有关，延长历史输入长度可以消除此负面影响。最后，附上了用于实现DMC仿真的MATLAB代码，但由于代码的实现方式较为复杂，通常建议使用Simulink+S-function进行闭环仿真，但此处无法提供完整的代码示例。
动态矩阵控制(dynamic matrix control, DMC)是模型预测控制(MPC)中一类具有代表性的算法。相比其它预测控制算法,MPC的主要特征在于利用了系统的阶跃响应模型。 假设t=0时刻u产生阶跃变化1,数学上为除0时刻的Δu(0)为1,其它所有为0:(1)Δu(t)={1,t=00,otherwise如图所示: ...
This example uses: Control System Toolbox Copy Code Copy Command Create a transfer function model. Get num = [4 2]; den = [1 3 10]; sys = tf(num,den); By default, the time unit of sys is 'seconds'. Create a new model with the time units changed to minutes. Get sys1 = ...
Linear frequency scale, the plot shows a single branch with a symmetric frequency range centered at a frequency value of zero. example bp = bodeplot(sys1,sys2,...,sysN) plots the frequency response of multiple dynamic systems sys1,sys2,…,sysN on the same plot. example bp = bodeplot...
Compute the zero-pole-gain (zpk(Control System Toolbox)) representation of the dynamic system. Evaluate the gain and phase of the frequency response based on the zero, pole, and gain data for each input/output channel of the system.
