What is fir1 in Matlab?
b = fir1( n , Wn ) uses a Hamming window to design an n th-order lowpass, bandpass, or multiband FIR filter with linear phase. The filter type depends on the number of elements of Wn .
What is FIRl function in matlab?
The firls function is an extension of the fir1 and fir2 functions in that it minimizes the integral of the square of the error between the specified frequency response and the actual frequency response.
What are Eigen filters?
Eigenfilters are FIR filters which are expressed in terms of a particular eigenvector of a matrix. The mathematical theory underlying their construction is attractive due to its simplicity and generality.
