The value of resistor creating thermal noise is doubled, the noise power generated is therefore—
-
- Halved
- Quadrupled
- Doubled
- Unchanged
- Halved
Correct Option: D
The noise power is given by expression
Pn = kTB
where,
k = Boltzmann’s constant
T = Temperature
B = Bandwidth
It means thermal noise is independent from the resistor creating thermal noise. Hence alternative (D) is the correct choice.
