The document explains the differences between analog and digital signals, noting that analog signals represent continuous time-varying quantities and are specific, with lower accuracy compared to digital signals. Digital signals, on the other hand, are comprised of discrete values (0s and 1s), allowing for more efficient processing and greater versatility. Overall, digital signals outperform analog signals in accuracy and reliability.
Analog and digital signal system : digital logic
- 2. The term Analog is a taken from “Greek” word “analogos”. Analog signals are a representation of time varying quantities in a continuous signal. Analog signals work with natural phenomena and physical values like frequency, earthquake, volcano, flow of water, speed of wind, weight, lighting etc.
- 4. Analog Device for Measuring Earthquakes
- 6. It works on continuous data. It is used to measure natural or physical values. It is specific to a particular task. Hence it is not versatile. Accuracy of analog signal is not high in comparison of digital signal. Analog signal output form is like Curve, Line or Graph, so it may not be meaningful to all.
- 7. The Digital signal having a discrete set of values. Digital signals are a series of ONs and OFFs (represented by 1s and 0s). These can be voltages going from a high (one) value to a low (zero) value or flashes of light. It is usually encoded into binary in order to carry out the information.
- 9. General purpose computer is best example of digital signal system based computer.
- 10. Digital Signal are continuous signals Digital signal based on binary form 0’s and 1’s Digital signal can be processed and transmitted more efficiently and reliable than analog signal. Digital signal are versatile, we can use digital signals widely than analog signals Accuracy of digital signal is higher than that of analog signal
