Introduction and Binary Ladder / R-2R Digital to Analog Converter26:24
This lecture deals with the basic concept of DAC ,its necessity and the idea behind the conversion of any Digital state to proportional Analog Voltage .It needs precise value of R and 2R hence any deviation in the resistance values creates error .
Binary Weighted Digital to Analog Converter Circuit12:43
This is the second type of DAC . The value of the resistances are in multiples of 2 and the voltage or current fed to the input is proprtional to the position of the bit in the binary number.
Simultaneous /Flash type Analog to Digital Converter20:07
This is the Fastest type Analog to Digital Converter .However as the resolution increases the complexity of the circuit increases.Hence for higher bits ADC -it is not recommendable.In this lecture we deal with this parallel type ADC.
Counter Type Analog to Digital Converter10:27
Counter type also known as Ramp type ADC uses a counter and comparator circuit to find proprtional digital state of an analog voltage .This will be slow and will take longer time to reach higher digital states as it always initializes from zero digital state.
Successive Type Analog to Digital Converter24:07
This is a revision of Counter Type ADC and for 4 Bit ADC -any digital state can be reached in 4 steps. Modern day semiconductor industries incorporate this circuit in IC's to perform the function .
Integrating Type ADC -Introduction and Single Slope Analog to Digital Converter28:49
These are Integrating type ADC - Single and Dual are two types.This lectures primarily focusses on the concept of Integration physical meaning in Electronics and then the topic is dicussed.
Dual Slope Integrating Type Analog to Digital Converter28:45
This is integrating type of ADC .Not the fastest one but definitely gives a precise conversion result .Its used when the error desired are less.These are used in Digital Multimeters ,DVM and other digtal circuits.

Description

In today’s world, almost every electronic device depends on signal conversion. When you speak into your smartphone, record music in a studio, measure temperature using a sensor, or monitor a patient’s ECG, Analog to Digital Converters (ADC) and Digital to Analog Converters (DAC) are working silently in the background.

This course gives you a clear, structured and practical understanding of ADC and DAC fundamentals, architectures, performance parameters and real-world applications. We start from the basics — analog vs digital signals — and gradually move toward sampling theorem, quantization, resolution, Nyquist criterion, SNR, INL, DNL and converter design techniques.

You will explore major ADC types such as Flash, Successive Approximation (SAR), Sigma-Delta and Dual-Slope, along with Binary Weighted and R-2R Ladder DAC architectures. Step-by-step numerical examples are included to help you solve exam and interview problems confidently.

The course also connects theory to practice with global industry examples from telecom systems, medical instrumentation, automotive electronics, embedded systems, IoT and audio engineering.

Whether you are an undergraduate student, postgraduate learner, electronics enthusiast or working professional, this course will build strong conceptual clarity and practical confidence in modern signal conversion systems.

By the end, you will not just understand ADC and DAC — you will be able to apply them.

Who this course is for:

Undergraduate students in Electronics, Electrical, Instrumentation, Communication, or Embedded Systems engineering who want strong conceptual clarity in ADC and DAC.
Graduate and postgraduate students preparing for university exams, competitive exams, research work, or advanced coursework in signal processing and communication systems.
Students preparing for technical interviews in core electronics, VLSI, embedded systems, telecom, and semiconductor industries.
Electronics hobbyists and makers working with Arduino, STM32, ESP32, Raspberry Pi, or other microcontrollers who want to understand how real-world signals are converted inside their projects.
Working professionals in telecom, automotive electronics, medical instrumentation, IoT, audio engineering, and industrial automation who need practical understanding of signal conversion.
Anyone curious to understand how smartphones, ECG machines, audio systems, sensors, and smart vehicles process analog and digital signals.
