Consider a link between two nodes. This link uses a transmission bandwidth

Consider a link between two nodes. This link uses a transmission bandwidth of 1 MHz. The transmitter wishes to digitize and send an analog video data of 4 MHz bandwidth at 20 mW. The signal through the medium experiences an attenuation (or loss) of 60 dB. So, the link provider uses an amplifier before the signal is received by the receiver. The amplifier doubles the input power such that P out = 2* P in, where P out and P in are measured in Watts. Assume receiver noise of -74 dBm. a.) What is the SNR (in dB) at the receiver?
