3. Introduction to ADC & DAC There are two types of data converters: # 1. Analogue to Digital Converter (ADC) # 2. Digital to Analogue Converter (DAC)

4. Topic 1.What is ADC and DAC Why we use ADC and DAC ? 2.​ Conversion steps for analog to digital conversion (Sampling, Quantization, and Encoding) 3.What is Quantization? What is Resolution of ADC ? 4. What is Sampling ? 5.Digital to Analog Converter 6. Types of ADC and DAC

6. Quantization :- it is the Process of assigning a Sampled Signal a Value from the discrete set of values. Encoding 10100101101

7. RESOLUTION Resolution 2^n

9.  PWM in DAC This is the type of DAC that most of us have used without even knowing it! The popular Arduino microcontroller has the capability to output analog signals using a PWM signal. On the outset the PWM signal looks like a binary waveform with only high and low peaks with a variable duty cycle (ratio of on time to time period).
