In digital signal processing, downsampling, compression, and decimation are terms associated with the process of resampling in a multi-rate digital signal processing system. Both downsampling and decimation can be synonymous with compression , or they can describe an entire process of bandwidth reduction ( filtering ) and sample-rate reduction.
Procyclical and countercyclical variables are variables that fluctuate in a way that is positively or negatively correlated with business cycle fluctuations in gross domestic product (GDP). The scope of the concept may differ between the context of macroeconomic theory and that of economic policy–making.
Business cycles are a type of fluctuation found in the aggregate economic activity of nations that organize their work mainly in business enterprises: a cycle consists of expansions occurring at about the same time in many economic activities, followed by similarly general recessions, contractions, and revivals which merge into the expansion ...
The cumulative process was the leading theory of the business cycle until John Maynard Keynes' The General Theory of Employment, Interest and Money. Wicksell's theory would be a strong influence in Keynes's ideas of growth and recession, in Gunnar Myrdal 's key concept Circular Cumulative Causation and also in Joseph Schumpeter 's " creative ...
Lucas's model dominated new classical economic business cycle theory until 1982 when real business cycle theory, starting with Finn E. Kydland and Edward C. Prescott, [8] replaced Lucas's theory of a money driven business cycle with a strictly supply based model that used technology and other real shocks to explain fluctuations in output. [9]
Biden is basically in a game of chicken with the business cycle. One tolerable scenario for him would have been to get a mild recession over and done with in 2023, so a recovery would be well ...
Real business-cycle theory (RBC theory) is a class of new classical macroeconomics models in which business-cycle fluctuations are accounted for by real, in contrast to nominal, shocks. [1] RBC theory sees business cycle fluctuations as the efficient response to exogenous changes in the real economic environment.
Upsampling requires a lowpass filter after increasing the data rate, and downsampling requires a lowpass filter before decimation. Therefore, both operations can be accomplished by a single filter with the lower of the two cutoff frequencies.
