Least squares method filter design

NettetTo create a finite-duration impulse response, truncate it by applying a window. By retaining the central section of impulse response in this truncation, you obtain a linear phase FIR … NettetA linear least squares filter makes an assumption that the input signal has a constant time derivative (fixed slope). If the input signal becomes a ramp, then this filter output …
