- Discuss the differences between analog data vs digital data.
- Discuss two type of compression techniques; lossy and loselss compression.
1. There is differences between analog data and digital data. One of the differences is signals which is analogue data shows that the signals is repetitive in physical measurements form but digital data signals is yet repetitive but its discrete in time which is digital modulation form.
2. There is two types of compression techniques such as lossy and lossless compression. This two techniques has the same reason of function but it works in a different way. Lossless can be implement by using coding method as the idea to access any transmition or storage in smaller form. Lossy is spatialy domain encoding which is definitely deleting unimporant bits of information to reduce the number of bits to become smaller.
