) g) What is the group delay of the filter and why it is important for filters to have constant envelop group delay> plot the group delay for both Filters. e) Repeat part (b) and (c) for the Chebsyshev Filter f) Compare between the FIR filter and the Chebyshev Filter (in term of delay, order, complexity, performance. d) Design a digital highpass Chebyshev Filter (Type I) with the same specifications of (a). ![]() Sketch the magnitude spectrum for the input and output files. Find the zero crossing bandwidth for each letter. c) Using window record to record two audio files with your voice (3 seconds each). What is the time delay associated with the filter (you can see that from the time domain signal). Filter Design and Analysis Tool (FDATool) of MATLAB for the purpose of designing. Convert the signal into audio file before and after the filtering. i tried to convert the matlab code to HDL code with HDL coder. I got the output for median filter in matlab and also in matlab simulink. Apply the filter to this signal and plot the signal magnitude spectrum before and after the filtering. Hi everyone, I want to design the median filter on FPGA. If you want zero phase distortion, use filtfilt. To use the filter on your data, you can either do filter(b,a,data) or filter(Hd,data) depending on what filter you eventually use. ![]() You can build upon these examples and mine to design a filter according to what you want. Give this all a try and see how it all works. You then use p.play to hear it in MATLAB. If you want to hear it played, you can construct and audioplayer based on this output signal at the same sampling frequency as the input. ![]() b) Construct a signal from x(t) = 2 cos(21(500)t) + 3sin(21(5000)t) sampled with Fs = 48000 sample/s and total duration of 3 s. The MATLAB documentation also has good examples on designing filters. You use filter to filter your signal using what you got from Step 6. Consider a minimum order FIR Filter with Kaiser Window. Then, the interface displays with a default filter. A) Using Filter designer tool in MATLAB design a highpass filter with cutoff frequency of 2.5 KHz and stop-band frequency 5 kHz with attenuation of 1 dB and 80 dB. A Tip of the Day dialog displays with suggestions for using Filter Designer.
