Abstract
We present a pedagogical introduction, including several new results, to Kac’s path integral solution for the telegrapher equation, with emphases on: 1) wave propagation especially waveform (signal) restoration (reconstruction), designing and prediction; and 2) the underlying Poissonian random walk (essentially an asynchronous telegraph signal), especially the measure, and the connection to Brownian motion.
