Example 2: calculate the RMS noise voltage arising from thermal noise in two resistors
100 & 150 resp. at T= 300°K within a bandwidth of IMHZ if:
a- The resistors are connected in series.
b- The resistors are connected in parallel.
Ex) A standard two-junction thermocouple configuration is being used to measure the
temperature in a wind tunnel. The reference junction is held at a constant temperature
of 10 °C. We have only a thermocouple table referenced to 0 °C. Determine the output
voltage when the measuring junction is exposed to an air temperature of 100 °C.
