I worked on this code
s=tf('s');
G=(s^3+11*s^2+36*s+26)/(s^4+14.6*s^3+74.96*s^2+156.7*s+99.65);
[A,B,C,D]=ssdata(G);
[AA, BB, CC,DD] = balreal(A, B, C);
[b,a] = ss2tf(AA,BB,CC,DD);
If i using the function 'ss2tf', i find this error :
Can any one help me how can i solve this...
I have a coefficients of FIR filter ,found it by 'fir1' function, in general, i want to convert a digital filter to transfer function with apply this formula :
The method :
Design a 48th-order FIR filter passband , with a cutoff frequency w=[0.35 0.65]. Compute the coefficients of the...
The first formula :
A causal first-order IIR filter is characterized by the following difference equation
(01)
The impulse response of that system can be computed via the Z-transform or otherwise, and it turns out to be
(02)
The second formula :
the general causal IIR filter is...
I try to design filter by using The mutation operator(One of the operation in genetic algorithm)
% parameter using in mutation operator
N=100 %population size
m=0.01 %mutation rate
% filter information
f = [0 0.3 0.4 0.6 0.7 1];
a = [0 0.0 1.0 1.0 0.0 0];
b = firpm(17,f,a);
A...
I want to understand ,''One of the most effective modifications of the direct LS error design methods is
to change the bands of frequencies over which the minimization is carried out.''
what i understood the change bands of frequencies is done by using the iteration method, am I right?
Digital filters are implemented using three fundamental building blocks: an adder, a multiplier, and a delay element.In implementation cost there is number of multipliers, number of adders and number of state.
Can you give more information about the implementation cost ? when using it?what is...
A generic causal FIR or IIR filter can be represented by the following transfer function in the z domain as
shown in
(01)
in other case, A finite-dimensional LTI discrete-time causal filter can be represented by the following transfer function in the z domain:
(02)
Why there is two...
The LS error methods use an error criterion that is related to the energy of
the signal or noise.
The design problem is posed by defining an error measure E as a sum (or integral) of the
squared differences between the actual and the desired frequency response over a
set of L frequency samples...
