Cyclic LTI systems in digital signal processing
Cyclic signal processing refers to situations where all the time indices are interpreted modulo some integer L. In such cases, the frequency domain is defined as a uniform discrete grid (as in L-point DFT). This offers more freedom in theoretical as well as design aspects. While circular convolution has been the centerpiece of many algorithms in signal processing for decades, such freedom, espe...

متن کاملDigital signal processing for an open-loop fiber-optic gyroscope.
Open-loop fiber-optic gyroscopes (FOG's) are generally less stable than closed-loop FOG's, yet they offer simpler implementation. We propose a modification of the harmonic division algorithm for an open-loop FOG, which is more stable and also simpler for implementation than the original one. It is shown that when the analog signal is properly sampled and quantized, the performance of our algori...
متن کاملMUS 424 : Signal Processing Techniques for Digital Audio Effects
There are typically four steps in producing a CD or movie soundtrack, as shown in Figure . In tracking sounds are recorded or synthesized and arranged in tracks. The tracks are then processed in the mixing stage to form a stereo or multichannel mix. The idea is to arrange the sounds spatially and spectrally, to manipulate their character for artistic purposes, and also to fix problems in the tr...
