In the context of data transmission, why is modulation necessary?
- To add redundancy to the data
- To improve data storage
- To increase the speed of data transmission
- To secure the data
Modulation is necessary in data transmission to increase the speed at which data can be transmitted over a communication channel. Modulation is the process of encoding digital data onto an analog signal, allowing it to be transmitted over long distances with minimal loss of signal quality.
