therefore i need to use Matlab and Simulink - (in order to run digital filters) the question is; can i use the both systems free or do i need to find another systems and programs to substitute the above mentioned to realize the project; matlab &/ Simulink - Simulation und Model-Based Design - MATLAB & Simulink
This example illustrates how to generate HDL code for a 5th order Butterworth filter. The cutoff-frequency for this filter is very low relative to the sample rate, leading to a filter that is difficult to make practical. Also, small input (8-bit) and output (9-bit) word sizes cause the quantized filter to require scaling to be realizable.
A signal 𝑥(𝑡) = 200 cos(48𝜋 × 103 ) 𝑡 is ideally sampled with a sampling period of 100 µsec and then passed through an ideal low pass filter with cutoff frequency of 30 KHz. Find the frequency is/are present at the filter output? Demonstrate the same using mat lab & simulink. Can you please tell me how to get started? Reply Delete
Title: Matlab Filter Analysis Author: ytang Created Date: 1/30/2007 1:35:49 AM
I went over and over again with MATLAB Help and google but couldn't find any solution. First of all, designing the bandstop filter, the help says : type:'stop' for an order 2*n bandstop digital filter if Wn is a two-element vector, Wn = [w1 w2]. The stopband is w1 < w < w2. Does that mean when i design my bandstop filter, the code should be :

What you are doing is, you "slow" the measurements down with a butterworth filter. Thus, in practice you try to get rid of the "fast" part. What this means in frequency domain is: you want a lowpass (low frequency = slow signal goes through, while high = fast gets filtered out).
View MATLAB Command. Design a 6th-order Butterworth bandstop filter with normalized edge frequencies of and rad/sample. Plot its magnitude and phase responses. Use it to filter random data. [b,a] = butter (3, [0.2 0.6], 'stop' ); freqz (b,a) dataIn = randn (1000,1); dataOut = filter (b,a,dataIn);

This example shows how to design classic lowpass IIR filters in Simulink ®. The example first presents filter design using filterBuilder. The critical parameter in this design is the cutoff frequency, the frequency at which filter power decays to half ( -3 dB) the nominal passband value. The example shows how to replace a Butterworth design with either a Chebyshev or elliptic filter of the same order and obtain a steeper roll-off at the expense of some ripple in the passband and/or stopband ...
