Hello everyone, I am Ashok Dirisam,
I have hands-on experience in Heavy Electronics and Electrical Control systems, PCB Repairing and Designing and Embedded systems,
My videos are a combination of my Knowledge and Experience in Electronics.
My videos are very useful for working professionals, Students, and Enthusiasts.
I am working hard to make my videos in a practical way rather than theoretical,
In my opinion learning in a practical way will clear all our concepts, Increases knowledge, and clears doubts.

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, Which 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 need ADC and DAC?
Most of the physical signals we find around us are analog in nature. For example temperature, sound, pressure, touch and etc. However, these analog signals have many disadvantages. Particularly when they are used in communication. The disadvantages of Analog signals are susceptible to noise and difficult to store and process.
On the other hand, Digital signals are less susceptible to noise, They are very easy to store and process.
That's why we use ADC and DAC.
Steps involved for the analog to digital conversion:
1. Sampling
2. Quantization
3. Encoding
In this video each step is explained, The Nyquist theorem and Aliasing effect are also explained with examples.
Important parameters for ADC and DAC
1. Resolution
2. Full scale range
3. Sampling time
4. Conversion time
5. Gain error and Offset error
6. Non-linearity
7. Accuracy
8. Total Harmonic Distortion (For DAC)
Types of ADC's :
1. Flash ADC
2. Dual Slope ADC
3. Successive Approximation Type ADC (SAR)
4. Sigma-Delta ADC
5. Pipelined ADC
Types of DAC's:
1. Binary Weighted Resistor Type DAC
2. R-2R ladder-type DAC
Applications of ADC's:
1. PLC's
2. Control systems
3. Smartphones
4. Audio Video devices and etc...
Applications of DAC's:
1. Digital printers
2. Measuring Instruments
3. Digital motor control
