According to an academic research, when an enterprise runs longer, their strategies are more prone to gain support by other businesses. Leaning on the durability and the longevity, such enterprises can accumulated their credits and stabilize the business. Consequently, the span variable of the total business-running time or the variable of growth rate and the price variable of stock exhibit a negative-proportion...
JPEG is a commonly used comparison algorithm in the real applications such as photographs, digital still camera images. Employing the multirate technique, the multirate JPEG (MrJPEG) with parameter R is developed to reduce the file size. The proposed approach provides a parameter R to trade off the image size and the image quality. Two examples are demonstrated in this paper. An image database including...
The frequency sampling method is very simple to design FIR filters with arbitrary frequency response. The generic problem of the FIR filter design via the frequency sampling method is to solve the normal equation accurately. A more explicit form to solve the coefficient matrix of the normal equation is derived in this paper. Both the mathematical derivation and the numerical verification are given...
In audio signal processing, there are three major sampling rates, 32 KHz, 44.1 KHz, and 48 KHz used in the audio signal processing. It is important to employ multirate signal processing techniques to remove imaging and/or aliasing in modern digital signal processing system with different input-output sampling rate. The application of equivalent multistage multirate sampling rate technologies can reduce...
In the traditional design of the M-band maximally decimated filter bank system, the resulting designed synthesis filters may be unstable. Based on the least square criterion and employing the calculus of variation and the spectral factorization techniques, a modified synthesis filter can be obtained. A causal stable synthesis filter bank is proposed to replace the conventional synthesis filter bank...
