What is meant by partition noise?
Toshi said:
1 decade ago
When a circuit is divided in between two or more paths then the noise generated is known as partition noise.

What is thermal noise and shot noise?
Jyoti said:

Shot noise: It arises in electronic devices (such as diodes and transistor) because of the discrete nature of current flow in the devices.
Thermal noise: This noise arises due to random motion of electron in the conducting medium such as resistor. It is also called resistor noise, Johnson noise, white noise.

@Raja.
Bipolar junction transistor. :. It is a current controlled device. It has 3 terminals. There are emitter, base, collector.
Two types : PNP and NPN.
