1 Calculate the SIN ratio for a receiver output of 4 V signal and 048 V noise both as a ratio and in decibel form

1. Calculate the SIN ratio for a receiver output of 4 V signal and 0.48 V noise both as a ratio and in decibel form. (69.44, 18.42 dB)

2. The receiver in has an SIN ratio of 110 at its input. Calculate the receiver's noise figure (NF) and noise ratio (NR). (1.998 dB, 1.584)

3. An amplifier with NF= 6 dB has SJ Ni of 25 dB. Calculate the S0 /N0 in dB and as a ratio. (19 dB, 79.4)

4. A three-stage amplifier has an input stage with noise ratio (NR) = 5 and power gain (Pc) = 50. Stages 2 and 3 have NR = 10 and Pc = 1000. Calculate the NF for the overall system. (7 .143 dB)
