Digital Filters
You will be able to: • Implement a digital filter in MATLAB. • Investigate how commercial filters work • Describe the transfer function of a filter Suppose the "raw" signal which is to be digitally filtered is in the form of a voltage waveform described by the function V = x (t) where t is time. This signal is sampled at time intervals h (the sampling interval). The sampled value at time t = ih...
متن کاملParamedic literature search filters: optimised for clinicians and academics
BACKGROUND Search filters aid clinicians and academics to accurately locate literature. Despite this, there is no search filter or Medical Subject Headings (MeSH) term pertaining to paramedics. Therefore, the aim of this study was to create two filters to meet to different needs of paramedic clinicians and academics. METHODS We created a gold standard from a reference set, which we measured a...
متن کاملQuantization Effects in Digital Filters
When a digital filter is implemented on a computer or with special-purpose hardware, errors and constraints due to finite word length are unavoidable. These quantization effects must be considered, both in deciding what register length is needed for a given filter implementation and in choosing between several possible implementations of the same filter design, which will be affected differentl...
متن کاملFractional Delay Digital Filters
The chapter goal is focused to introduce the concept of fractional delay filters (FDF), as well as a concise description of most of the existing design techniques. For this purpose, several illustrative examples are presented, where each design method is implemented by MATLAB programs. A fractional delay filter is a filter of digital type having as main function to delay the processed input sig...
