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

5. 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

8. STREAMING MUSIC ON SMARTPHONE

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

28. R2R DAC

29. • 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).
