To be precise the group delay of a linear phase FIR filter is ( N − 1) / 2 samples, where N is the filter length (i.e. the number of taps). The group delay is constant for all frequencies, because the filter has a linear phase, i.e. its impulse response is symmetrical (or asymmetric). A linear phase means that all frequency ...

WebA new application of the LMS adaptive filter, that of determining the time delay in a signal between two split-array outputs, is described. In a split array sonar, this time delay can be converted to the bearing of the target radiating the signal. The performance of such a tracker is analyzed for stationary broad-band targets. It is shown that a continuous adaptive … Web30 de ago. de 2002 · Time delay estimation is very important in many applications such as radar, sonar, communication, geological exploration, biomedical engineering, etc. We propose a SINC filtering algorithm (SFA), i.e., one based on the sinc function. The algorithm can get an accurate time delay estimate with little or no prior knowledge about …

This has nothing inherently to do with your method of … Web4 de ago. de 2024 · Second, the sampled signal is reconstructed, and then a finite impulse response (FIR) filter is designed to compensate for the time delay. There are several advantages of the proposed method compared with previous works: the convergence with a BP network is faster, the estimation accuracy is higher, and the calibration does not …
WebCompared to IIR filters, FIR filters offer the following advantages: They can easily be designed to be “linear phase” (and usually are). Put simply, linear-phase filters delay the input signal but don’t distort its phase. They are simple to implement. On most DSP microprocessors, the FIR calculation can be done by looping a single ...
