The easiest way is to use the freqz function, found in the matlbal
signal processing toolbox.
If you have the polynomial coefficients of both numerator and
denominator of your h(z) function, respectively num and den, typing
freqz(num,den) will plot H(f) in module and phase.
Hope this helps.

How can I get Frequency Response from Impulse Freponse In Matlab?
Hi! I want to get FRF of IIR Filter from Impulse Response. So, I got FRF using two method. One is FREQZ, another is FFT of impulse response. But two results are different. Why? My source code are below : clear all close all clc fs=2048; % Sampling Frequency N=65536; % Buffer Size t=[0:N-1]'./fs; % Time f = [0:N/2]'*fs/N; % Frequency x = zeros(N,1); % Impulse Input Signal x(1)=1; % 1 pole butterworth highpass filter with 2.7 Hz Cutoff [B, A] = butter(1, 2*2.7/fs, 'high'); [h, f] = freqz(B, A, N, fs); h = abs(h(1:N/2+1)); h_mag = 20*log10(h); f = f(...

Calculate frequency response of Z transform with known frequency bins
Hi all, I've been searching for the best way to do this programmically, but I can't seem to come up with a simple solution. I have a program that calculates filter coefficients correctly based on this z-transform: H(z) = (b0+b1*z^-1+b2*z^-2)/(1+a1*z^-1+a2*z^-2) I want to be able to display the magnitude response of this filter from 20Hz-20kHz at specified frequencies (48pts per octave) which I already have defined. Basically, I want to be able to pass in a frequency, lets say 250Hz, and be able to return a value based on what the filter is doing magnitude wise at that frequency assuming the sampling rate is 48kHz. Any help would be appreciated.

Depending on the type of lattice filter you have (FIR, IIR), the various forms of the latc2tf() function will convert the lattice filter reflection coefficients and ladder taps into the equivalent numerator/denominator coefficients that you would use in a direct-form implementation. You can then pass these values into freqz() to see the frequency response. Jason yijun_lily@yahoo.com wrote: > Many stages, is there any easy way to get the response?

Using Matlab to elegantly calculate frequency response
Another question related to my low-pass filter. Basically, I can calculate the frequency response of the circuit, one frequency at a time, using Matlab; what I can't figure out is how to use this method to calculate the response for a whole bunch of frequencies at once. Maybe someone can help me out. Here are the calculations for a single frequency at a time: EDU>> % The circuit analysis calculations are: EDU>> % (Vin - V2)/R2 + (Vout - V2)/c2 = (V2 - Vout)/R4 EDU>> % (V2 - Vout)/R4 = Vout/c1 EDU>> % Re-arranging.... EDU>> % V2*(-1/R2 - 1/c2 - 1/R4) + Vout*(1/c2 + 1/R4) = -Vin/R2 EDU>> % V2*(1/R4) + Vout*(-1/R4 - 1/c1) = 0 So the goal is to set up a matrix: Vm * V = Vr, and then calculate: V = inv(Vm) * Vr. Again, for a single frequency: EDU>> f=2500; EDU>> w=2*pi*f; EDU>> R2=330; EDU>> R4=1000; EDU>> c1=1./(j.*w.*470e-9); EDU>> c2=c1; EDU>> Vin=1; EDU>> Vm = [(-1/R2 - 1/c2 - 1/R4) (1/c2 + 1/R4) ; (1/R4) (-1/R4 - 1/c1)]; EDU>> Vr = [ -Vin/R2 ; 0 ]; EDU>> V=inv(Vm)*Vr; EDU>> abs(V) ans = 0.37972 0.050967 The second value for "ans" correctly matches the measured output from the circuit at f = 2500 Hz; it also matches the result if I use the following equation to calculate the output voltage: EDU>> % Some pencil and paper work then yields EDU>> % Vout = (Vin/R2) / [(R4/c1) * (1/R2 + 1/c2) + 1/c1 + 1/R2] So far, so good.

Frequency Response between SS coded by Matlab and Result in Time Domain
Hi All, I try to validate the frequency response of my state-space model with the result from time domain simulation. Let me tell you what I have done: 1. My state-space model (named ss_Mo) is coded by Matlab and it is MIMO (4 inputs, 4 outputs). To get the frequency response I use command >>bode(ss_Mo). Then I will get the 32 graphs (16 for gain in decibel, 16 for phase). Each input provides 4-gain and 4-phase curves. Q1.If I want to choose only one gain and one phase, how can I use command to select only the interesting curves and replot them? Gain should be in decibel and the range...

Output of variable known, impulse response is known, how to get input signal in matlab?
Hello all, I have an oxygen sensor that has reported back oxyge concentrations while moving in a yo-yo pattern through the ocean. I have a vector of oxygen concentrations (about 10000 entries or more) and a vector of corresponding time intervals (approximately constant every 2 seconds). I consider my o2 concentration the output signal y(t). I know the sensor responds exponentially, so we are assuming an impuls response h(t)=[1-(e^-t/tau)] where tau is our time constant ~ 24seconds. Can anyone out there suggest how I would go about solving for the initia input signal x(t)? I assume this can be done in matlab, perhaps the signa processing toolbox. Any help, references, comments are welcome. cheers, - Charlie Charlie wrote: > Hello all, I have an oxygen sensor that has reported back oxygen > concentrations while moving in a yo-yo pattern through the ocean. > > I have a vector of oxygen concentrations (about 10000 entries or more) , > and a vector of corresponding time intervals (approximately constant ~ > every 2 seconds).

Frequency response, impulse response and fft
I'd like to compute frequency response functions (FRF) from impulse response functions (IRF). I thought that the Matlab fft function would do the job. However, it is not working as I expected. I wrote a script that computes the IRF of a 1-DOF mechanical system, storing it in a vector. Then, the FRF vector is found by fft-ing the IRF. However, when this result is compared with the analytical FRF vector, we see that the two vectors are very different. Please, could you help me to figure out the mistake I'm doing? The Matlab code is: clear all close all % System properties m1=1; k1=500; c1=5; wn1=sqrt(k1/m1); zeta1=c1/m1/2/wn1; wd1=sqrt(1-zeta1^2)*wn1; % Impulse response t=linspace(0,10,1000); h=1/m1*1/wd1*exp(-zeta1*wn1*t).*sin(wd1*t); % FRF from impulse response H=fftshift(fft(h)); Fs=1/(t(2)-t(1)); f=linspace(-Fs/2,Fs/2,length(t)); % Analytical FRF w=2*pi*f; G=1./(k1-m1*w.^2+sqrt(-1)*w*c1); % Results figure(1) semilogy(f,abs(H)/length(H),'-r',f,abs(G),'-b') legend('from IRF','analytical') grid xlabel('Freq.

ishandle(h) vs. try(get(h))

In fact, ishandle will return 1 (true) for any vector of 0's. In my case I was able to work around this by using the following, try(get(a)), fprintf('Handle Found\n'); catch, fprintf('N...

Numerically Computing Impulse Response from Power Frequency Response
I am trying to compute the impulse response of a given channel to include in a BER analysis. I have the power transfer function of the channel, not the classical amplitude/phase transfer function of the channel. Fortunately, the transfer function is symmetric, so I can numerically calculate the impulse response as: amp_freq_resp = sqrt(power_freq_resp); imp_resp = ifft(amp_freq_resp); imp_resp = real(imp_resp); The final command simply removes the imaginary portion of the impulse response, as it is only an effect of the IFFT calculation in MATLAB. The square root can be used because the transfer function, so the impulse response will be purely real. This is where the problem arises. The power transfer function is near Gaussian, and so is the amplitude transfer function. This would imply that the impulse response should be near Gaussian. However, because I am taking a finite length IFFT, the impulse response is a Gaussian convolved with a very high frequency sinc function. So I get a Gaussian envelope with alternating positive and negative values in my impulse response. Of course, this sort of impuse response is terrible for certain modulation types. My question is, can I simply calculate the envelope of the impulse response and use that as the impulse response in my BER analysis? If not, is there any method that I can use to easily remove the effects of the finite-length IFFT from the impulse response? Thanks, Susheem susheemg@yahoo.com wrote: > I am trying ...
