sig = dpcmdeco(indx,codebook,predictor)implements differential pulse code demodulation to decode the vectorindx. The vectorcodebookrepresents the predictive-error quantization codebook. The vectorpredictorspecifies the predictive transfer function. If the transfer function has predictive order M,predictorhas...
pulse code modulationIn this paper, we present an approach for investigating the pulse code modulation for signals with various shape forms. We have developed an algorithm as well as its course of implementation in MATLAB and Octave environments. The software we have implemented makes it possible ...
Luis F.Chaparro, inSignals and Systems using MATLAB, 2011 12.4.1Pulse Code Modulation PCM can be seen as an implementation of analog-to-digital conversion of analog signals providing a serial bit stream. This means that sampling applied to a continuous-time message gives a pulse amplitude–modul...
This MATLAB function returns the complex envelope of the modulation of the input message signal, x, using PAM and the alphabet size, M.
Set the pulse repetition frequency (PRF) equal to the inverse of the modulation period and set the sampling rate to 10 times the inverse chip width. Initialize the waveform with the first code. fs = 10/tau; % Sample rate pmwaveform = phased.PhaseCodedWaveform('SampleRate',fs,'Code','...
A MATLAB Model of Hybrid Active Filter Based on SVPWM Technique A method for active filter having hybrid feature is discussed in this paper. The method uses space vector pulse width modulation (SVPWM). In the proposed control method, the Active Power Filter (APF) reference voltage vector is ge...
When the value at port G is between 0 and 1, the averaged switch is partly opened. You can then average the PWM signal over a specified period. This allows for undersampling of the model or using modulation waveforms instead of PWM signals....
