I am designing a fractional delay filter, and my lagrange coefficient of order 5 h(n) have 6 taps in time domain. I have tested to convolute the h(n) with x(n) which is 5000 sampled signal using matla
I\'m french so I\'m sorry if you have trouble to unders开发者_JAVA技巧tand some of my sentences.
I have IR sensor which have TRS connector and I can record my remotes signals into audio. Now I want to control my computer with TV remote, but I don\'t have any clue how to compare audio input with p
I am designing a music visualiser application for the iPhone. I was thinking of doing this by picking up data via the iPhone\'s mic, running a Fourier Transform on it and then creating visualisations
I\'m currently developing a percussion tutorial program. The program requires that I can determine what drum is being played, to do this I was going to analyse the frequency of the drum recording and
I have simply pitch detection. Input (microphone) data are passed to fft routine, then I\'m looking for a pitch with maximum value It means:
I am trying to use Excel\'s (2007) built in FFT feature, however, it requires that I have 2^n data points - which I do not have.
I have some periodic data, but the amount of data is not a multiple of the period. How can I Fourier analyze this data? Example:
I analyzed the sunspots.dat data (below) using fft which is a classic example in this area. I obtained results from fft in real and imaginery parts. Then I tried to use these coefficients (first 20) t
After searching for FFT code in java I have come across three classes that do the job, read the wav file,
