Low wall filter

Web3 nov. 1994 · Abstract: In medical ultrasound, flow velocity estimation for blood flow imaging (color flow) relies on first filtering out signals due to stationary scatterers so that a simple autocorrelation frequency estimator can be used to determine flow. Usually, this “wall filter” is implemented as either a conventional FIR or IIR filter. Unfortunately, in the case of … An ideal low-pass filter completely eliminates all frequencies above the cutoff frequency while passing those below unchanged; its frequency response is a rectangular function and is a brick-wall filter. The transition region present in practical filters does not exist in an ideal filter. An ideal low-pass filter can be realized mathematically (theoretically) by multiplying a signal by the rectangul…
