Description : Define ADC and DAC. Write two applications of each.

Answer : ADC An analog to digital converter (ADC), converts any analog signal into quantifiable data, which makes it easier to process and store, as well as more accurate and reliable by ... signal, hence any analog circuit can work with digital system Application - Microcontroller, washing machine

Description : What is the need of data converters? List specifications of DAC.

Answer : Need of data converters:  It is often necessary that before processing the analog data, by a digital system, it should be changed to an equivalent digital form. Similarly, after processing the data, it ... 4. Temperature sensitivity 5. Settling time 6. Speed 7. Long term Drift 8. Supply rejection

Description : Digital to Analog Converter (DAC)

Answer : Digital to Analog Converter (DAC) Digital means binary (1 0) and 1 and 0 may be true and false or on and off or high and low. Analog means continuous signal or information ... wave. Phase Shift Keying (PSK) is transmit digital data by changing the phase of carrier wave.
