1. GDP measures both the total income of everyone in the economy and the total expendi- ture on the economy's output of goods and services. GDP can measure two things at once because both are really the same thing: for an economy as a whole, income must al expenditure. As the circular flow diagram in the text illustrates, these are alter- native, equivalent ways of measuring the flow of dollars in the economy

Complementary Filter(CF) Often, there are cases where you have two different measurement sources for estimating one variable and the noise properties of the two measurements are such that one source gives good information only in low frequency region while the other is good only in high frequency region

ow that we've reviewed the various bonding models, we are ready to examine organic compounds in respect to their structure, reactions, properties, and appli cations. Were we to list the physical and chemical properties of each of the more than million organic compounds separately, it would tax the capacity of even a pow- erful computer. Yet someone who is trained in organic chemistry can simply look at the structure

N ow that we're familiar with the structure and preparation of alkenes, let's look at their chemical reactions. The characteristic reaction of alkenes is addition to the double bond according to the general equation:
