This online textbook introduces a powerful analytical framework for designing systems across engineering disciplines, from electronics to mechanical and thermal applications. Derived from MIT’s foundational Signals and Systems course (6.003), it takes a modern perspective. While traditional courses emphasize continuous-time analog circuits, today’s engineers rely primarily on digital technology and discrete-time simulation.

A graph illustrating signal sampling where a smooth, continuous gray wave curve moves horizontally along a time axis, t. Red vertical arrows of varying heights rise from the axis to capture discrete values of the function f(t) at regular intervals marked by black dashed lines.
An illustration of the process of signal sampling, a fundamental step in converting analog signals to digital data. (Courtesy of Petr.adamek on Wikimedia Commons. Image is in the public domain.)
