Extracted text: Thermal noise is a type of noise that is produced when electrons move rapidly and randomly within a conductor due to thermal agitation. Determine the following for an amplifier operating at a temperature of 27°C and a bandwidth of 20 kHz. Assume that the ambient temperature is 290 Kelvin. (i) the thermal noise power in watts and dBm. (ii) the RMS noise voltage for a 60 Q internal resistance and a 60 Q load resistance. (iii) the increase in thermal noise power in dB if the temperature increased to 70°C. (iv) the increase in thermal noise power caused by doubling the bandwidth.
