In the work the difference equations are entered
for the analysis of linear radio systems. Canonical scheme based on the entered
of equations is constructed. Under this scheme digital filters are
classified as recursive, non-recursive and complex. According to the method of
multipliers Lagrange weights coefficients of nonrecursive digital filters of
arbitrary order are optimized.
Coefficient of improvement the transfer
function of the notch filter is analyzed.
