FSK Demodulator
Hi folks, I manage a hardware engineering group for a telcom company and I am beginning to look around for FPGA IP to implement both FSK modulation and demodulation. I am wondering if any of you have any experience with any of the IP around today. The demodulator is the most difficult part and I believe the fol... 2 Jul 2008 21:10

Rectangular Window Advantage
Hi All, I read in this book DSP with Computer Applications that the rectangular window (used for windowing ) gives the best approximation to the desired frequency response in a least square sense. That is, it gives the least squared, integrated, error between the Hd(W) and Ha(W) for a given number of impulse respon... 1 Jul 2008 16:27

Fourier Series Simulations
If I were to simulate a signal by using the Fourier series synthesis equations and some distributional assumptions on the amplitude and phase, would I be able to generate a signal that was representative of real life signals? Thanks ... 1 Jul 2008 18:30

LMS algorithm implementation
I am currently doing research in Active Noise Control. I am quite new in this field. I have acquired some knowledge in Adaptive filtering. I also read about a few daptive algorithms. To start with I am interested to simulate a feed forward Active Noise Control System incorporating simple LMS algorithm. Anybody ... 8 Jul 2008 07:57

Problem building CCS project using flash files.help needed
I am currently working on burning my CCS program on to flash. According to Mr. Rulph Chassaing, this is done in the regular sequence( i.e. by adding libraries,asm files, C files,linker file, and the header files).He then says that we need to replace the asm file and the command linker file with the files ... 1 Jul 2008 11:17

Biquad cascade
I was wondering what the most computationally efficient way of implementing a biquad cascade would be? I've implemented an alsa application to generate the filter coefficients and process some audio. This works great on my linux machine, but when I put the same code on a less powerful embedded system, it sounds ... 2 Jul 2008 00:38
