Which type of signal is more reliable and why?

Digital signals are a more reliable form of transmitting information because an error in the amplitude or frequency value would have to be very large in order to cause a jump to a different value. Signals are composed of infinite possible values. Signals are composed of only two possible values: 0 or 1.

What are the 2 main functions of signal processing?

Feature extraction, such as image understanding and speech recognition. Quality improvement, such as noise reduction, image enhancement, and echo cancellation.

What are the three types of signal processing?

Signal Processing Applications

Data acquisition and signal processing. Digital image and graphics processing. Video compression and signal processing.

What are the limitations of signal processing?

Disadvantage of Digital Signals :

Processor speed is limited. Develop quantization and round-off errors. Systems and processing is more complex. A higher bandwidth is required for data communication in comparison to analog transmission of an equivalent information.
