Answer to Question #298665 in Electrical Engineering for Eli

Question

1. What is the open-circuit noise voltage across a 100-kΩ resistor over the frequency range of direct current to 20 kHz at room temperature (25°C)? 

2. The bandwidth of a receiver with a 75-Ω input resistance is 6 MHz. The 

temperature is 29°C. What is the input thermal noise voltage? 

3. What is the average noise power of a device operating at a temperature of 90°F with a bandwidth of 30 kHz?
