It establishes a sufficient condition for a sample rate that permits a discrete sequence of samples to capture all the information from a continuoustime. Network theorems acwaveforms superposition theorem one of the most frequent applications of the superposition theorem is to electronic systems in which the dc and ac analyses are treated separately and the total solution is the sum of the two.

We shall show h ormanders l2proof the following theorem of newlandernirenberg. As is universally known, the proof amounts to expanding by the binomial theorem and noting that for 0 trees. The shannon information theorem shows us the possible channel capacity in bits per modulation symbol increases as the snr increases with a fixed bandwidth. Integration is the subject of the second half of this course. These compression procedures can be deduced in view of the shannons expansion formula. Thevenins theorem states that any two terminal linear circuit containing a large number of voltage andor current sources and resistors can be replaced by a simple equivalent circuit containing a single voltage source and a series resistor. Williamson these remarks have their origin in a conversation i had with edwin zimmerman about two years ago.

In fact, the application of each theorem to ac networks is very similar in content to that found in this chapter. Then we will look at an explicit and very handsdown construction of a code due to elias 1 that achieves a positive rate for some positive crossover probability. We cannot prove the theorem, but can partially justify it as follows.
