The physical meaning of Fourier transform

is easy to find, and the form and positive transformation are very similar;3. Sine basis function is the Eigen function of differential operation, so that the solution of the linear differential equation can be transformed into the solution of the algebraic equation with constant coefficients. The convolution operation with constant clutter is a simple product operation, thus providing a simple method for calculating convolution.4. The well-known convolution theorem points out that the Fourier

Analysis of Java Reflection mechanism

Currently, there are few places in the project to use the Java reflection mechanism (except the spring framework), but for subsequent preparation, it is simple to summarize the recent reflections as follows:1. By reflection in optics, the reflection in Java can be interpreted as "mirroring". Has the following uses:The Java reflection mechanism mainly provides the following purposes: Determine the class to which any object belongs at run time

Time-domain and frequency-domain transformation --- mathematical derivation of Fourier Series

the following "orthogonal basis" composed of an infinite number of trigonometric functions (including constants, Fourier series expansion is actually just an action, that is, to "project" the function to a series of "coordinate axes" composed of trigonometric functions. (3 ). Sine and Cosine are second-order partial differential equations (Equations containing capacitor and other components), while capacitors can communicate through DC. (4 ). First, we will introduce the Fourier series formula

Pcba defect Solution

Many processes are involved in the pcba process, and each process may have quality defects. These quality problems always involve many aspects and are difficult to solve. Due to the causes of the problems, some belong to chemistry, machinery, plates, Optics and so on. After decades of production practice, combined with the practical experience in solving quality and relevant materials on solving technical problems, the following is a summary: Pcba Pro
