I wasn't the one who was taking personal shots.. I just asked for how do I decide filter specifications from a given graph...You don't even know me and you could were questioning my credibility..

I meant in MATLAB, the FDA tool is a tool in MATLAB to design filters! But it only creates a filter as per my specifications, how do i test it with an input is what I asked? Any idea about that?

I have a pretty good idea about filters, what I am not very good is MATLAB and dude, seriously, this post wasn't binding on you to answer! Fine, I suck at practical implementation of theoretical concepts but dude, chill! Yeah, I am pretty good at theoretical concepts (and that doesn't mean book...

i didn't ask to help me understand how to read the ECG! I merely asked how are to determine the filter specifications. As for the my work, I did the following, since the sample includes 150, 000 samples and we don't really need all of them. Since the sampling freq is 1000Hz, we can take up any...

can you please tell me how do I filter a signal? I mean the signal output as given in the attached file is plotted. Now if i design a filter using FDA Toolbox, how am i supposed to test that filter for this signal input?

just give me something to start with...

actually I am not able to understand what am I supposed to do. I mean, okay, i copied the signal in MATLAB and plotted it, it comes out as shown in the figure. I have to design two filters, band stop and a high pass filter to attenuate the noise in the signal. I know that the bandstop...

I have no idea what is to be done. Please help! I do not how am I supposed to proceed/begin as well. The zip files contain a data collected from an ECG machine and the pdf has the problem statement. Any kind of help would be much appreciated. Thanks

up and down sampling means increasing or decreasing the sampling frequency!

Homework Statement Does the upsampling and downsampling have any effect on the amplitude? consider the following X(e^jw) Homework Equations what will be the amplitude of the signals? do they remain 1 or are they to be divided/multiplied by L/M, L being upsampling factor and M...

@salzrah Why did you remove the answer? is it wrong or what?

Kindly see the question above. First signal is x[n] Ques 1: we are required to find x[4-n] The way I did, the answer should be (a) but one of the solution says (b). Which is the correct one?Ques 2: What are we to do while finding x[2n]? Consider only 0, 1 and 2 as twice of those gives 0, 2...
