The main aim of this paper is to compare
and evaluate frequency methods applicable for
discrete-time (DT) linear time-varying (LTV)
systems, in particular: two-dimensional (time,
frequency) transfer function (2D-TF), timeaveraged
2D-TF and approximated Bode diagrams
calculated using SVD-DFT approach and power
spectral density (PSD) properties. The main
evaluation criteria is possible applicability to
feedback system stability analysis. The paper
begins from short theoretical background of
frequency methods applicable for LTV systems.
Further properties of these methods are compared
and discussed on the basis of particular case of
parameter controlled switching DT LTV system.
