If you don t want aliasing, the sampling rate should be above twice the start of the high frequency stop-band of whatever filter you can find to use before the sampler.
波纹所居住的环境物理往往提供自己的低绕或波段过滤器(播送损失、转子损失等)。 如果你能够确定这种天然过滤器的切碎,使其停波段低于你所期望的噪音,那么你可以使用这种频率超过2X。
如果你不关心别 alia,那么任何样本都会照相,但频率会越低,结果的带宽越小,加上该带宽的多层别 alia。
我只想以不同的取样率聆听瓦夫案卷,并寻找其自然而然的取样率。
I have two waveforms which are linked by a numerical factor. I need to use optimal scaling (least squares) between the two waveforms to calculate this factor in Matlab. Unfortunately I have no idea ...
I’m trying to implement a Blind Source Separation (BSS) algorithm and I’m running into trouble determining the efficacy of the algorithm. I’m trying to create test cases where I work backwards and ...
采用什么最佳方法选择马特拉布数字过滤器设计特性与全球数据分析仪的过滤器? 更具体地说,如果我有信号,我如何确定哪些过滤价值......。
I m looking for a book similar to "Introduction to Algorithms" by Thomas Cormen geared towards DSP algorithms. Is there anything as thorough as Cormen on the DSP market? EDIT I should say I m ...
I need to do some basic and non basic DSP programming in C#. At its core, it includes the generation of a sin wave deciding its frequency in Hertz. Then I d like to Frequency Modulate it and maybe ...
What is the best filter to use to remove noise from an ECG signal with matlab?
I m new to DSP programming, and I m wondering how best to carry out the seemingly basic operation of level adujustment. Say I have an 8 bit number that represents the amplitude I want a signal to be ...
I would like to write a little application in VB.NET that will detect a baby s cry. How would I get started with such an application?
