We will assume here that the independent variable is time denoted by and the dependent variable could be any physical measurementvariable which changes over time think for example of a time varying electric voltage We will denote the generic measur ID: 26784 Download Pdf

Analogue to Digital Conversion. Quantizing. Encoding. Pulse Code Modulation. DEFINITION: . Pulse code modulation (PCM) is essentially analog-to-digital conversion of a special type where the . information .
5. Speech Coding. Low Bit-rate Voice Coding. Voice is an analogue signal. Needed to be transformed in a digital form (bits). Speech signal is not random=>can be encoded using fewer bits as compared to random signal.
How do we represent a continuously variable signal digitally?. Sampling. Sampling rate – number of measurements per unit time. Sampling depth or . quantization . – number of gradations by which the measurement can be recorded.
