Extracted text: Determine the noise figure in decibels and equivalent noise temperature for the non- ideal amplifier that has the following parameters. Assume that the ambient temperature is 290 Kelvin. (b) Input signal power = 2.0x10-10 W Input noise power = 3.5x10-17 W Power gain of the amplifier = 10 Internal noise power (generated in the amplifier) = 5.5x10-12 W A specified gain of 9 dB and a noise figure of 4.5 dB are specified for an amplifier. What is the equivalent noise temperature in Celsius? Then, if three identical amplifiers are cascaded together, determine the overall effective noise figure and noise temperature. Assume that the ambient temperature is 290 Kelvin. (c)
