## What is sampling and quantization in ADC?

An analog-to-digital converter (ADC) can be modeled as two processes: sampling and quantization.

Sampling converts a time-varying voltage signal into a discrete-time signal, a sequence of real numbers.

Quantization replaces each real number with an approximation from a finite set of discrete values..

## How is ADC value calculated?

ADC has a resolution of one part in 4,096, where 212 = 4,096. Thus, a 12-bit ADC with a maximum input of 10 VDC can resolve the measurement into 10 VDC/4096 = 0.00244 VDC = 2.44 mV. Similarly, for the same 0 to 10 VDC range, a 16-bit ADC resolution is 10/216 = 10/65,536 = 0.153 mV.

## What is full form of SP?

SP full form is Superintendent of Police (पुलिस अधीक्षक). In India, a Senior Superintendent of Police (SSP) in large or metropolitan cities or Superintendent of Police (SP) in smaller cities is the head of the police force of a district.

## What is ADC in ICT?

Short for ‘Analogue-to-Digital Converter’. Computers can only deal with binary or digital data, whereas much of the data collected by sensors is analogue data. An ADC converts the analogue data into digital data so that the computer can process and store the data.

## What is ADC in bank?

The term Alternate Delivery Channel (ADC) generally used for Alternate Service Delivery Channel (ASDC) or Alternate Banking Channel (ABC) in the Banks for its services to the customers. Channel means the system of intermediaries between the producers, suppliers, consumers, etc., for the movement of a goods or service.

Why do we need Analog to Digital converters? In the real world, most data is characterized by analog signals. In order to manipulate the data using a microprocessor, we need to convert the analog signals to the digital signals, so that the microprocessor will be able to read, understand and manipulate the data.

## Which is the fastest ADC and why?

The most common types of ADCs are flash, successive approximation, and sigma-delta. The flash ADC is the fastest type available. A flash ADC uses comparators, one per voltage step, and a string of resistors. A 4-bit ADC will have 16 comparators, an 8-bit ADC will have 256 comparators.

## What is meant by ADC?

Stands for “Analog-to-Digital Converter.” Since computers only process digital information, they require digital input. Therefore, if an analog input is sent to a computer, an analog-to-digital converter (ADC) is required. A common use for an ADC is to convert analog video to a digital format. …

## What is the main function of a D or ADC converter?

The main purpose of the A/D converters within a data acquisition system is to convert conditioned analog signals into a stream of digital data so that the data acquisition system can process them for display, storage, and analysis.

## What is difference between DAC and ADC?

In simplest terms, it’s this: an ADC is attempting to capture and convert a largely unknown signal into a known representation. In contrast, a DAC is taking a fully known, well-understood representation and “simply” generating an equivalent analog value.

## What is sampling time in ADC?

The sampling time is the ADC clock cycles for which the sample and hold capacitor is charged up to the channel input voltage. The ADC then requires another 12 clock cycles to convert to 12 bits accuracy.
