What is encoding in adc

Encoding is the process of converting the quantized signals into a digital representation. This encoding is performed by giving each quantization level a unique label. For instance, if four bits are used, the lowest level may be (in binary) 0000, and the next highest level 0001, etc.

What is encoder in ADC?

In an ADC, encoder is employed to convert thermometer code to binary code. In this paper, a 4-bit encoder is proposed to be used in the flash ADC. The efficiency of an encoder is measured on the basis of two parameters: PDP and EDP.

What is quantization and encoding in ADC?

Quantizing: It is the process in which the reference signal is partitioned into several discrete quanta and then the input signal is matched with the correct quantum. Encoding: Here; for each quantum, a unique digital code will be assigned and after that the input signal is allocated with this digital code.

What is signal encoding?

The signal encoding, called 4D-PAM5, consists of four symbols, each of which contains two bits. All four wire pair are used to transmit signals in each direction, so 8 bits are transmitted at a time. A hybrid is used to separate transmission in each direction, similar to what is done in conventional analog telephony.

Is ADC a codec?

In the embedded hardware world, the term CODEC stands for COder/DECoder and is basically an analog-to-digital converter (ADC) and a digital-to-analog converter (DAC) in one package.
