Chebyshev vs. Butterworth Filters: Speed, Quality Factor, and Making the Right Choice Introduction: When it comes to selecting a filter for signal processing, Chebyshev and Butterworth filters are two of the most popular options. Both filters have their unique strengths and weaknesses, and choosing the right one can greatly impact the effectiveness of your signal...
Introduction In this post i want to talk about zero-lag filters, how they interact with the price and its frequency components. I'll also talk about the phase-response, and try to clearly explain how it works and what information it can give to the user. I'll finally introduce the concept of forward-backward filtering as well as zero-phase non stable causal...
Introduction The gaussian filter don't see many uses in technical analysis and financial data smoothing in general, however it possess really interesting properties and a really close relationship with the simple moving average. The gaussian filter is a filter which possess a function approximately gaussian (bell shaped curve) as : impulse response, step...
Introduction Digital signal processing (dsp) is used to manipulate signals and extract information from them. Among all the tools available, digital filters are the most common ones to use, in fact you are certainly using one during your analysis. In this post i will share some of the knowledge i have associated with filters and their properties. I will try...
