In cryptography, Caesar's code (or Caesar's encryption, Caesar's transformation) is one of the simplest and most widely known cryptographic techniques. It is a technique for replacing encryption, in which all letters in plaintext are replaced by a
this bug. People who write this topic usually seem very busy, or those who know the details of this topic will remain silent. This allowed me to spend several hours exploring more information about the mystery on the first day of the New Year (New Year's Day), And I pieced together these pieces of information.
Note that this is a highly correlated event. Therefore, the main description of this event is speculation, unless the ban is canceled for a while. What I see, including the suppliers invo
Ω P = 0.3pi, the boundary frequency Ω S = 0.5pi, and the band attenuation delta s is not less than 50db.
Method 1: manually calculate the Order N and β values of the filter, and then design the filter through the program.
Step 1: Calculate the order B and β values of the filter based on the transition band width and impedance band attenuation.
Step 2: design the filter through programming.
The procedure is as follows:

There is also a ready-made design function:
B = FIR1 (M, Wn, 'type', window );
B is the coefficient vector of the filter to be designed. The length is n = m + 1;
M is the order;
Wn is the edge frequency, scalar or array given by the filter;

How to Implement the password cracking program of CaesarWith the recent development of security, the study of cryptography is becoming increasingly important.Asymmetric password system, but due to processing and other important reasonsIt is widely used, such as shift. The basic idea of substitution remains unchanged. I personally think that in the futureWithin a long time, we will certainly spend a lot of time researching cryptography
History of principal component analysis:Pearson was proposed in 1901 and then developed by Hotelling (1933) as a multivariate statistical method. Through the main components of the analysis to show the largest individual differences, but also to reduce the number of regression analysis and clustering variables, you can use the sample covariance matrix or correlation coefficient matrix as a starting point for analysis.By linear combination of the original variables, the optimized index is obtaine

Because the frequency-domain resolution of long blocks is high and the time-domain resolution of short blocks is high, long blocks are more suitable for relatively stable time-domain signals, while short blocks are more suitable for time-domain signals with relatively fast changes.
The length of a long block is 2048 points, and the length of a short block is 256 points.
