Signals and systems covers analog and digital signal processing ideas at the heart of modern communication and measurement we present the basic concepts for continuoustime and discretetime signals in the time and frequency domains time and frequency are related by the fourier transform
The kuband system provides a much higher gain signal with a smaller antenna than the sband system the orbiters kuband antenna is gimbaled so that it can acquire the tdrs upon communication acquisition if the tdrs is not detected within the first 8 degrees of spiral conical scan the search is automatically expanded to 20 degrees
