Question

______________ is caused due to thermal interaction between the free electrons and the vibrating ions in the conduction medium.

Answer 1

thermal noise is caused

Answer 2

Answer:

Thermal noise is caused due to thermal interaction between the free electrons and the vibrating ions in the conduction medium.

Explanation:

1. Noise is an undesirable and unwanted quantity. It has an effect on the signal received in a communication system.
2. Noise is caused by spontaneous fluctuations rather than erratic interruptions in optical fibre communication networks.
3. The random migration of free electrons in a conductor caused by thermal agitation causes thermal noise.
4. The motion's magnitude is related to the conductor's temperature.
5. The random travel of the electrons causes a random current to flow through the conductor, resulting in a random noise voltage across the conductor's terminals. The average power Pave, which is a function of the temperature of the conductor T and the width of the frequency range B included in the measurement, is used to determine the magnitude of thermal noise.
