5. a. Calculate the S/N ratio for a receiver output of 3 V signal and 0.45 V noise both as a ratio and in decibel form. b The receiver in Problem 5a has an S/N ratio of 100 at its input. Calculate the receiver's noise figure (NF) and noise ratio (NR). c. An amplifier with NF= 4 dB has S/Ni of 20 dB. Calculate the S/No in dB and as a ratio.
