Q5 (a) You are required to design a cascaded network that contains of THREE (3) amplifiers. If the network produces an output of 800 mV for 20 mV input, draw a diagram that shows this network with appropriate power gain of each amplifier (A1, (5 marks) Using the power gain value (A1, A2, A3) you have set in Q5(a), if the input signal power and input noise power of the network are 3x10-W and 2x10-15 W respectively and each of the amplifier has internal noise (Nd) of 4x10-12 W: (b) i. Calculate the output SNR of each of the amplifier (5 marks) ii. Use Friss formula to determine the total noise figure, NFT (10 marks) Q5 (a) You are required to design a cascaded network that contains of THREE (3) amplifiers.
