In a superheterodyne receiver, the incoming RF signal is at 25 dBµ. the RF amplifier has a 30 dB gain, the mixer has a 10 dB loss, the IF amplifier has 20 dB gain and the demodulator has a 5dB loss. What is the AF level at the output of the demodulator? (Assume that noise in each block is negligible) a.90 dBµ b.40 dBµ c.30 dBm d.60 dBm
