Introduction to ADC and DAC

In this video, the basics of Analog to Digital Converter (ADC) and Digital to Analog Converter (DAC) have been discussed. By watching this video, you will learn the following topics: 0:00 Introduction 0:20 What is ADC and DAC? Why we use ADC and DAC? 3:30 Conversion steps for analog to digital conversion (Sampling, Quantization, and Encoding) 3:58 What is Quantization? What is the Resolution of ADC? What is Quantization Error? 9:42 What is Sampling? (Criteria for sampling and the need of Anti-aliasing Filter ) 12:49 Digital to Analog Converter and important parameters for DAC 13:53 Types of ADC and DAC What are ADC and DAC? ADC stands for Analog to Digital Converter, which converts the analog signal into the digital signal. DAC stands for Digital to Analog Converter and it converts the Digital signal into an analog signal. ADC and DAC are an essential part of our life and by some or other way we are using in our day to day life. Why we use ADC and DAC? Most of the naturally occurring signals are analog in nature. The analog signals are susceptible to noise and difficult to store and process. And the digital domain, it is easy to store and process these signals. That's why for storage and processing signals are converted into digital form and it is retrieved using DAC. Steps involved for the analog to digital conversion: 1. Sampling 2. Quantization 3. Encoding In this video, each step is explained briefly and how the error is introduced during the process is also explained. Important parameters for ADC and DAC 1. Resolution 2. Reference Voltage 3. Conversion and/or settling time 4. Gain and Offset Error 5. Non-linearity (Differential and Integral Non-linearity) 6. Accuracy 7. Total Harmonic Distortion (For DAC) Types of ADC : 1. Flash ADC 2. Dual Slope ADC 3. Successive Approximation Type ADC (SAR) 4. Sigma-Delta ADC Types of DAC: 1. Binary Weighted Resistor Type DAC 2. R-2R ladder Type DAC This video will be helpful to everyone in understanding the basics of ADC and DAC (What is ADC and DAC, How it Works and Important Parameters of ADC and DAC). #ADC #DAC #AnalogtoDigitalConvertor #DigitaltoAnalogConverter Follow me on YouTube:    / allaboutelectronics   Follow me on Facebook:   / allaboutelecronics   Follow me on Instagram:   / all_about.electronics   Music Credit: http://www.bensound.com/
