2.4. A receiver is made up of three cascaded stages each with a gain of 10 dB and each with a noise figure of 3 dB. a. Calculate the overall noise figure. b. Calculate the overall noise figure if only the input stage degrades so that its noise figure becomes 6 dB. c. Calculate the overall noise figure if only the output stage degrades so that its noise figure becomes 6 dB. Discuss the reason that your answer is smaller than in Part (b). 2.4.
