Question

Difference between pulse modulation and digital modulation

Answer 1

Answer:

The method which transforms a digital signal to an analog signal is called "digital modulation". Digital modulation provides high data security and information to its users. It has three types.

1- Amplitude shift key

2- Frequency shift key

3- Phase shift key

The information processed in the form of discontinuous signals is known as "pulse code modulation". Based on the type of information it has two categories.

1- Pulse analog ( information is processed in the discrete form)

2- Pulse digital  (information is processed continuously)

Answer 2

Explanation:

Explanation:

Sublimation is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage. ... The opposite of sublimation is "deposition", where water vapor changes directly into ice—such a snowflakes and frost.
