1.) An amplifier has three amplification stages and a 1-dB attenuator in cascade. Assuming that all impedances are properly matched, what is the overall gain if the amplification factors are5, 10, and 6dB? Express the answer in decibels and in non decibal form.
2.) A signal level of 145μV is found across a 50-Ωload. What is the signal level expressed in dBm?
