Abstract
The basic methods of detecting individual tonal components and algorithms for their implementation are considered; their advantages and disadvantages are analyzed. A generalization of the one-bin sliding parametric discrete Fourier transform is proposed. The algorithm implementing this transformation significantly reduces the number of operations required for the algorithm to enter the sliding measurement mode.
