johnson noise meaning in Hindi

Examples

1. Johnson noise converts heat energy into electrical energy the reverse of resistance.
2. Photomultipliers offer the best possible opportunity to exceed the Johnson noise for many configurations.
3. The corresponding fluctuation is Johnson noise.
4. It interpolates between shot noise ( zero temperature ) and Nyquist-Johnson noise ( high temperature ).
5. Thermal noise, specifically Johnson noise, involves uneven distributions of electrons or other charged particles in a system.
6. In a given frequency band, the noise-power has equal contributions from every frequency and is called Johnson noise.
7. If a detector is limited by either shot noise or Johnson noise then the NET can be decreased by using an increased integration time.
8. As with Johnson noise, it limits, for any given setup of electrical equipment, how accurately you can measure the current running through an electrical device.
9. The idea was the diode would rectify the Johnson noise thermal current flucuations produced by the resistor, generating a direct current which could be used to perform work.
10. With analog filters, every component is a source of thermal noise ( such as Johnson noise ), so as the filter complexity grows, so does the noise.
