1. The Successive-approximation converter has a longer conversion time when compared with the digital-ramp converter. 2. The ADC converts analog input to a digital output. 3. The DAC converts analog input to a digital output. 4. Most physical variables are analog in nature and can take on any value within a continuous range of values. 5. A transducer is a device that converts an electrical variable to a physical variable. 6. The microcontroller is the brain of an embedded system, which orchestrates all the operations. 7. Microcontrollers consume less power and have no need for a cooling system. 8. Microcontrollers (MCU or C ) are different from microprocessors (MPU).
