Extracted text: In TV receivers, the antenna is often mounted on a tall mask and a long lossy cable is used to connect the antenna and reciever. To overcome the effect of noisy cable, a preamplifier is mountedon the antenna. The parameters of the diffrent stages are Preamplifier gain Preamplifier noise figure Lossy cable noisy figure Cable loss =20 dB = 6 dB :3 dB = -20 dB Receiver front end gain Receiver noise figure Determine the overall noise figure of the system, 360 dB 16 dB
