Methods of noise reduction
3 Reducing the source impedance (if possible) gives two benefits: Reduction in thermal noise voltage Reduction in capacitive interference coupling (see later) Example: Using 20 kHz bandwidth, a 1 MΩ sample at room temperature generates thermal noise of 20 µV. Reducing the resistance to 10 kΩ would reduce it to 2 µV.
