FAQs on Introduction to ADC and DAC Video Lecture - Analog and Digital Electronics - Electrical Engineering (EE)
| 1. What is the purpose of an ADC and a DAC in electrical engineering? |  |
Ans. An ADC (Analog-to-Digital Converter) is used to convert analog signals into digital data, while a DAC (Digital-to-Analog Converter) is used to convert digital data back into analog signals.
| 2. How does an ADC work? | |
Ans. An ADC works by sampling the analog input signal at regular intervals, quantizing each sample into a digital value, and encoding it in binary form for digital processing.
| 3. What are the key differences between an ADC and a DAC? | |
Ans. The key difference between an ADC and a DAC is that an ADC converts analog signals into digital data, while a DAC converts digital data back into analog signals.
| 4. What are the applications of ADC and DAC in electrical engineering? | |
Ans. ADCs are commonly used in digital audio systems, data acquisition systems, and communication devices. DACs are used in digital audio systems, video processing systems, and motor control systems.
| 5. How do the resolution and sampling rate of an ADC affect its performance? | |
Ans. The resolution of an ADC determines the number of discrete values it can represent, while the sampling rate determines how often the analog signal is sampled. Higher resolution and sampling rates result in better accuracy and fidelity in the digital conversion process.
