An ideal voltage source of 1mV is in series with a 1 kOhm resistor.The temperature in the resistor is 300 H, and the bandwidth of the system is 100 kHz. What is the S/N ratio of the output signal?
I know that the S/N ratio is 10 log (Ps/Pn) dB where Ps and Pn s signal- and noise power. Ps = V/R^2, right? But what is Pn?
