Hi, why Does MATLAB FIR1 function use -6 dB cutoff frequency instead of -3 dB ? I am using MATLAB 6.5 version. I am trying to design a LPF with the help of FIR1 function. n = 51; % order of the filter wn = 0.4 % cutoff frequency fir1(n,wn); freqz(b); Now my cutoff frequency should come on the -3 dB level but it is on -6 dB level.

I am learning how to use the GUI Wavelet program in Matlab (newbie). I am working out an example and notice the following graphs labeled : S, A1, A2, A3, A4, A5 and D1, D2, D3, D4, and D5. I am performing a level 5 decomposition. I am sure S = original signal but what does A1 to A5 and D1 to D5 mean? I assume its 1 to 5 because its a level 5 decomposition but I am not sure what A and D st...

In Matlab, I have a room impulse response. I need to plot a frequency response from 20 to 20k Hz, smoothed to 1/3 and 1/6 octave. I can calculate the ISO octave center frequencies. I see lots of RTA software that does this real-time. Anyone have the Matlab code that does this, or provide the algorithm? Thanks.

Dear all, I am trying to model a multipath in matlab but I do not have the communications toolbox and so neither the raileighchan function. I would appreciate your help on assessing if my approach to generate the FIR discrete channel is correct. I have two vectors containing the complex gain and the delay of each path in my channel, taps_gain and taps_delay and a variable, Ts, containi...

Hello all, I am an EE university student and want to simulate the physical layer of a GSM communications system in MATLAB. I have studied several papers and resources on the web,but I think that I am missing something. Below, I will try to illustrate my approach, which tries to follow the quadrature baseband method presented in http://www.emc.york.ac.uk/reports/linkpcp/appD.pdf, pages 6-11. Co...

Hello, I recently bought that book. It says the Matlab scripts and C code listings are in www.wiley.com/college/kurzweil However, when I try to go to that site, it fails, nothing comes out. Does somebody have those programs (Matlab and C code), and is willing to share, or could tell me how to get it? Thanks, JaaC

Hello, I am using the MATLAB 'actxserver' function to establish a connection to RTDX(for real-time data exchance between MATLAB and a DSP board) and if say 'h' is my activex object, I use invoke(h) to get a list of functions I can use in that interface. There are some functions that have "pointer(variant)" or something similiar as the argument to the function. Anybody know what these are an...

Hi! I am a newbie on DSP working on a project which involves using a few different kinds of loudspekers so I have to be able to equlize them. The plan is to do that using a FIR filter. All implementation is done in MATLAB. I have not been able to find any good matlab examples on this matter. I have got this far: 1. Got a nice 128 samples impulse response. 2. I use the rceps function to get...

Can anyone help me do scaling for matlab's mscohere? I have two time series x and Y of the same length (1x220) which I want to know the relationships spectrally. mscohere gives me the coherence (cxy) with a vector (1 x 146) which is lower than the length of x or y. I can't explain it, so is there anyway I can make a better plot where I can derive any meaning? The peaks are ok ranging from 0-1. ...
