Figure 1 shows a three stage amplifier circuit. Sin = -15 dB AMPLIFIER AMPLIFIER AMPLIFIER 2 3 Nin = -50 dB AP, = 8 dB NF, = 4 dB AP2 = 10 dB NF2 = 5 dB AP3 = 12 dB NF3 = 6 dB = Figure 1: Three Stage Amplifier Determine the followings: (a) SNR input of Amplifier 1. (b) Total noise figure of the three stage amplifier circuit. (C) SNR output of Amplifier 3. [2 marks] [6 marks] [2 marks]
