    How Does Linear Predictive Coding (LPC) Reduce Bandwidth in Speech Coding?

    Hi there mgb_phys, I went through the webpage earlier. Unfortunately it does not say how exactly the LPC reduce the bandwidth. I mean the version of the LPC is VSELP, right ? But, what are the processes involved ? Does the Levinson-Durbin algorithm can be matched to answer the question ? Or...

    Scaled Drawings for Science Report on Cantilevers

    Hi there, My suggestion would be to have the measurements and the scales correctly printed, even though it is just a presentation in the report. By the way, you have nothing to loose if they are not graded, but what is those small miniture things matters to the examiner ? Anyway, did you...

    How Does Linear Predictive Coding (LPC) Reduce Bandwidth in Speech Coding?

    Hello everyone, Question : One version of Linear Predictive Coding (LPC) has been adopted as a standard for speech compression in mobile communications systems. How Linear Predictive Coding (LPC) can reduce the bandwidth in this speech coding ? Can someone please help me with this...

    Pulse Code Modulation - Understanding Digital Transmission

    Hi everyone:smile:, This is my question: " Describe the concepts of PCM (Pulse Code Modulation) in a computer keyboard which its data are in digital format." This is my justification: How to describe the concepts of PCM ? Isn't PCM a technique used to transmit analog signals in digital...

    Bandwidth Req: Digital vs Analogue Signals

    Hello Friends, Thanks for the reply. I am still confused with the whole Nyqusit theorem. Anyway, I understood about the sampling and also about the harmonics. Thank you very much. Take care. Bye bye.

    Bandwidth Req: Digital vs Analogue Signals

    Hi, I would like to know why do the digital signals require more bandwidth than the original analogue signals to convey the same information ? Is it something to do with the Nyquist Theorem or Shannon's Law ? And what about the harmonics ? Thank you.
