ABSTRACT
Annotation. Chapter 4 deals with forced oscillations in a linear system driven by
a non-sinusoidal external force, namely by a force with square-wave time depen-
dence. It includes a description of the simulated mechanical physical system and
its electromagnetic analogue, and a summary of the relevant theoretical material
for students as a prerequisite for the virtual lab “Square-wave Excitation of Linear
Oscillator.” Chapter 4 also includes a set of theoretical and experimental prob-
lems to be solved by students on their own, as well as various assignments that the
instructor can offer students for possible individual mini-research projects.
