用MATLAB作切比雪夫-1型低通滤波器设计(Using MATLAB for-1 Chebyshev-type low-pass filter design)

设计一CQMFB，低通滤波器H_0 (z)来自一半带滤波器。该半带滤波器的长度为47，通带截止频率ω_p=0.42π，试给出H_0 (z)，H_1 (z)，G_0 (z)，G_1 (z)的幅频响应，单位抽样响应并画图。试着产生一信号，它由两个正弦加白噪声组成，一个在低频，一个在高频，正弦的频率及和白噪声的信噪比自己给定。试用所设计的滤波器组对该信号进行分解和重建。比较重建后的效果，并对结果继续进行分析。(Design a CQMFB, low pass filter H_0 (z) the half-band filter. The length of the half-band filter 47, passband cutoff frequency ω_p = 0.42π, try to give H_0 (z), H_1 (z), G_0 (z), G_1 (z) of the amplitude-frequency response, the unit sample response and Paint. Try to generate a signal that consists of two sinusoidal composition plus white noise, a low frequency, a high frequency in the signal to noise ratio, frequency and sine and white noise of its own given. Trial designed filter group that signal decomposition and reconstruction. Results were rebuilt, and the results continue to be analyzed.)

this program deals with homomorphic analysis of speech. it was homework assignment in digital speech processing course. speech is synthesized using homomorphic filter.

mlvessel is a Matlab package for retinal vessel segmentation. The package can be used in two different manners: through the graphical user interface or through script invocation. Use through script invocation relies on input files and produces both file and html output. You may also download a stand-alone executable corresponding to the graphical user interface at our website mentioned below, though some functionalities are only available through script invocation.

nearestSPD works on any matrix, and it is reasonably fast. As a test, randn generates a matrix that is not symmetric nor is it at all positive definite in general.
