hai every one,First of all thanks for all your quick response t=0:0.05:5;X=1+sin(pi*t); plot(t,X) Since ,the required o/p is 1(in time domain). I thought if i should get the o/p as 1, the LP filter coefficients had to be designed in such a way so as to get the reqiured o/p as 1. i multiplied with x(t) and y(t) with u(t) [step function] x(t)=[1+sin(pi*t)]u(t) ; y(t)=u(t) I took Laplace tra...

I think that the mandatory upgrade is overrated. I am still using Acrobat 6.0 and often get a warning that the document I am opening is not compatible with the version of Acrobat I am using. But it is very seldom that I actually find a problem viewing a document. The only one that comes to mind are the data sheets from Silicon Blue. Some of those actually can not be viewed using

Hi I am sorry for repeating my question. .. I have a data from 3 different data sets. Each dataset has a periodicity in itself . 1st: 1 4 7 10 13 16... 2nd: 2 6 10 14... 3rd: 5 10 15 20.... but after combining my data sets , its like: 1 2 4 5 6 7 10 13 14 15 16... How can I determine the sampling rate from given data, so that I can calculate the filter coefficients? In case my d...

Hello for this newbie question! I'm on developing a simple audio-sequencer application. So, if I want to play a 44100Hz samplesound with a default note at D4 like a drum at lower notes like C4,F3,E3,etc., I have to decimate to the according sampling-rate. But of course, to prevent aliasing, there must be a lowpass filter before decimation. The best way to to this very efficient is an FIR-...

For CD signals (sampling rate 44100Hz), Butterworth method is applied to design 10 bandpass filters. Center frequencies of these 10 bands are: 31, 63, 125, 250, 500, 1K, 2K, 4K, 8K, 16KHz, respectively. As weighting values (0.5, 0.5, 0.5, 0.8, 1.1, 1.3, 1.6, 1.6, 1.6, 1.6) are set to these corresponding 10 badns, the "Full Treble" style of music is achieved. It seems that the function of "Ful...

After six and a half years, I still get email about my article "PID Without a PhD" (http://www.wescottdesign.com/articles/Sampling/pidwophd.html) from people who are asking for clarifications, or are asking questions that go beyond what I could say in the 5000 word limit that Embedded Systems Programming magazine imposed. The one I got today made me think. It didn't make me think b...

This isn't DSP per se, but still related - I was reading Charles Wheelan's book, where he makes the good point that "lying with statistics" is more often due to bad data, than poor dats processing; i.e. it's esential to gather unbiased samples from the population. But this motivates the question: is this ALWAYS true? Are there any circumstances where a researcher would delibera...

Hi, I have a question related with the OFDM transmitter. What is the commonly method to increase the sampling rate ? - Increasing the IFFT size and insert zero in the inpput ? or - Insert zero in the IFFT output and followed by interpolation filter ? What is the trade-off ? anyone can help ? Thanks. Buzz

Hi, I want to set a few things clear in my head and was hoping you could help. Sawtooths have an infinite number of harmonics, so am I right in saying that a DAC can only represent harmonics with frequencies equal to or below the Nyquist limit? In other words, if I have a sampling rate of 1000Hz, and I wish to output a sawtooth with a fundamental frequency of 200Hz, then the best I could ho...

Hello People, I have been facing this problem for last so many days. I would be very thankful to you if you can guide me. I want to simulate doppler, which can be present in underwater communicatons. Now, I have designed one algorithm based on linear interpolation to correct doppler and it works fine for real data. It corrects the doppler also. But now I have modified my transmitter and r...

Hi all, I am facing the following difficulty. In order to view the spectrum F(w) of a signal x(t), I have to sample it and then take DFT on computer. F(w) is infitely supported. In order to decide the spacing of sampling, I need to figure out a bandwidth that contains 99% of total energy of F(w), which is denoted as 2B. Thus within 1% of truncation error, I will be able to say th...
