In a Link Loss Budget, minimum system loss equals which expression?

In a Link Loss Budget, you’re making sure the signal at the receiver stays within what the receiver can handle. The system gain tells you how large the signal would be at the receiver input if there were no losses, while the receiver’s dynamic range defines the usable range of input levels—from the minimum needed for detection up to the maximum before distortion or overload. If the system gain pushes the signal toward or beyond that maximum, you must introduce some loss to keep it within range. The smallest loss that achieves this is the difference between the total system gain and the receiver’s dynamic range. So the minimum system loss equals system gain minus the receiver’s dynamic range. For example, with a system gain of 40 dB and a receiver dynamic range of 18 dB, you’d need at least 22 dB of loss to stay within limits.
