What is the basic principle of analog-to-digital converter?

What is the basic principle of analog-to-digital converter?

The basic principle is that the input signal Vi is compared with an internal staircase voltage, Vc generated by a series circuit consisting of a pulse generator (clock), a counter counting the pulses and a digital to analog converter, converting the counter output into a dc signal.

What is the process of converting from analog-to-digital called?

The process of converting an analog signal to a digital signal is called Modulation.

What is the function of an analog-to-digital converter?

An analog-to-digital converter (ADC) is used to convert an analog signal such as voltage to a digital form so that it can be read and processed by a microcontroller.

How does an electrical4u analog to digital converter work?

by Electrical4U From the name itself it is clear that it is a converter which converts the analog (continuously variable) signal to digital signal. This is really an electronic integrated circuit which directly converts the continuous form of signal to discrete form. It can be expressed as A/D or A-to-D or A-D or ADC.

How does an ADC convert an analog signal to a digital one?

ADC performance needs will also reflect the capabilities and requirements of the other signal processing elements in the loop. An ADC samples an analog waveform at uniform time intervals and assigns a digital value to each sample. The digital value appears on the converter’s output in a binary coded format.

How many discrete values does a digital to analog converter have?

But for output (digital) of an N-bit A/D converter, it should have only 2 N discrete values. This A/D converter is a linkage between the analog (linear) world of transducers and discreet world of processing the signal and handling the data. The digital to analog converter (DAC) carry out the inverse function of the ADC.

How is dithering used in an analog to digital converter?

The undistorted signal may be recovered accurately by averaging over time. Dithering is also used in integrating systems such as electricity meters. Since the values are added together, the dithering produces results that are more exact than the LSB of the analog-to-digital converter.
