ADC introductions for beginner

1. What is ADC?

An ADC, also called AD Converter, is a device for conversion of analog signal to digital signal.

ADC converts inputted voltage values to outputs numerical values.

(ex) Inputted Voltage   numerical values.(Digital values)
  0V 0(0000)
  0.5V 7(0111)
  1V 15(1111)

2. Analog signals and Digital signals

based on digital signal of AV devices

3. Resolution of ADC specifications

The ADC is a ruler of voltage and resolutions is the scale on a ruler.

The required resolution varies from applications or equipment.
Video Signals:8 to 12bits
Audio Signals :16 to 24bits
(ex.)Video Signals

4. Conversion rate of ADC specifications

The digital signal is discrete for a direction at time. It need a sampling.

The required rate of conversion varies from applications or equipment.
Video Signal:around 10MHz to 200MHz
Audio Signal : around 10kHz to 200kHz

(ex.)Video Signal
In case of 1080p-FHD
An analog to digital converts pixel data(2200×1125=247.5Mpixel) of 1 screen while 1/60 sec.
The rate of conversion needed 148.5MHz.

(according to the Nyquist–Shannon sampling theorem)
It can be revitalize an original analog signal by sampling at frequency 2 times as analog input signal band.

5.ADC Specifications for applications

The rate of resolution and conversion needed varies from usages.

Optimized AD conversion method varies from rate of resolution and conversion
