Random Process and Noise – geeksforjobs

Hey all, Welcome to Geeksforjobs

Random process:

The random process is a family of two variable_play space and time functions.

Random process classification:

There are mainly four types of random processes:

• Discrete random process
• Continuous random process
• Continuous random sequence
• Discrete random order

Random Process Type:

In practical situations, random processes can be classified into different types based on their frequency components.

• Low pass random process
• Bandpass random process
• Bandlemmed random process
• Narrow random process

Static properties of random process:

• The statistically random process has three properties
• Pisces
• autocorrelation
• Cross correlation

Ergodic process:

The random process that satisfies the ergodic theorem is called the ergodic process.

Noise:

• Noise can be defined as an unwanted electrical signal.
• Many disturbances of an electrical nature create noise in communication systems.

Noise Classification:

• Noise is classified into two groups based on the source.
• 1. External noise
• 2. Eternal Noise

External noise:

Noise whose sources are external to the receiver is called external noise.

type:

• Atmospheric noise
• Supernatural noise
• Industrial noise

Internal noise:

Noise created within a system is called internal noise.
