# Information: Part 2 - Gaussian Distribution

Information can never be separated from its nemesis, which is uncertainty. The former is only possible by limiting the latter.

Fig. 1 - Probability and odds are just different ways of expressing the same thing.

Fig.2 - At a) a rectangular probability function is shown. Two such functions convolve to form a triangular function b). As more functions are added, the familiar Gaussian curve c) emerges.

Fig.3 At a) a noisy signal has a voltage distribution shown here. The proportions of signal and noise at any instant are unknown, so the precise value of the original signal is unknown. At b) a binary signal can suffer bit errors when noise causes the voltage to cross the threshold.

Fig.4 At a) the distinct distributions due to the two conditions suggest a strong link between them and the outcome. At b) the broad distributions show that something else is affecting the outcome and our assumption about the effect of the applied conditions may not be correct.

# Information: Part 3 - Applying Statistics

We are not done with statistics yet. In a sense we will never be done with it and it is better to know how to deal with it than to ignore it. It is better still to know how others…

# Transforms: Part 5 - OFDM

Thus far we have looked at transforms from a somewhat abstract viewpoint. In contrast, here we look at an application where transforms take center stage.

# Electricity: Part 3 - AC Systems

Here we look at alternating current (AC) systems and how generating AC often requires an intermediate step of converting to DC to improve the efficiencies of AC generators.
