ok kral.
i think i got what you meant. Thanks. i have a hard time choosing what is a reasonable value for fp.Thats why want to consult you on that.
If i get the correct value for fp.Similarly,how do i get fs for the lowpass prototype filter?
regards
scdoro
thanks mimomod for your help.
btw, i have another question which i am stuck in how to begin..It is in the attachement.
Qn) what should be the reasonable value which i should choose for 'fp in "step 2"?
I have devise steps below for the approach.Can you help me see if its correct
steps:
1)...
hi kral,
thanks for the reminder.
Do you know what reasonable values i should take for fp'? The passband frequency of the prototype lowpass filter.
Another issue which i will like to confirm is that is ωu and ωl referring to these 2 sets of frequencies. one set is (fs1,fs2) and the other set...
Hi all,
i have to compute the normalized arithmetic round-off noise error for a direct form II realization of an IIR digital filter.
For a Form II realization, there are 2 adders, so there will be two errors altogether.Assuming that the error values are the same on both adders,
Qn1) The first...
Hi all,
Can someone help me with this design question, i have worked out the steps to do the problem.
Can someone help me scanned through it and see if i missed out anything.
Qn) what should be the reasonable value which i should choose for 'fp in "step 2"?
steps:
1) Required to find the...
Re: How to implement 12 bit fixed point representation in Ma
Okie. thanks for the guide.
I think it helps me to learn about the filter design toolbox.i plot the fixed point filter and the original filter on the same magnitude response graph and i got this result in the attachment. It seems...
matlab fi function fix points
hi all,
i have a question here and i am done with the first part on designing the bandpass filter by writing a matlab script below.

Okie.thanks for your help. i managed to get the form for the cascade expression.
But i still have problem getting the expression for the parallel form. Can you help me with this?
thanks
Hi all,
Can someone help me to express the given transfer function in a cascade and parallel form. Please see the attachment for the transfer function.
Qn1)Upon expansion of the transfer function, i will get
{(9.75) + (7.2375z^-1) -(37.770625z^-2) + (18.69735z^-3) } in the numerator. I...
Hi again,
see attachment for my actual question.
I have found the result of the FFT of x is found to be
[0,-0.83536j,0,0.1464j,0,-0.1464j,0,0.8536j].
From here we can see that it is made up of 2 sine wave components.
given by x(t) = Asin(2Πf1t) + Bsin(2Πf2t).
Q1)And now i need to determine...
hi all,
suppose i have a complex number of a signal as = 2+3i.
i need to express it in terms of Asin(ωt)
Qn1) how do i calculate the frequency,f of this signal?
Qn2) how di i calculate the amplitude A of this signal?
thanks

Hi all,
Can someone help me to prove this question without using Matlab.
I have found the sampled signal x to be
x=[0 0.125 0.25 0.125 0 -0.125 -0.25,-0.125] since 8 samples in 1 secs.
Qn1) since the sampled signal is x=[0 0.125 0.25 0.125 0 -0.125 -0.25 -0.125]
we can actually show that...
FFT
hi all
can some one guide me on how i can find the unknown for A,B,f1, and f2 by using an 8-point FFT? Should i be using DIF FFT or DIT FFT?
regards
scdoro
hi everyone,
can someone help me to troubleshoot this question?
********************************************
i drew the graph for the analog signal.its a triangular waveform with freq,f1=1hz.
The signal is sampled at fs=8hz and reconstructed using ideal reconstructor.
what i did was...
