Über die Nachbildung und Untersuchung von Abtastsystemen auf einem elektrischen Analogrechner
A 1960 journal article (reprint AH 507) by G. Schneider of the AEG Institute for Automation, Frankfurt, published in Elektronische Rechenanlagen Vol. 2, pp. 31–37. The paper presents a new method for simulating sampled-data (pulsed-data) systems on an electric analog computer, covering the construction of both sampling elements (using relays and RC circuits) and difference-equation elements (via cascaded sampling units acting as delay-line synthesizers). A detailed worked example demonstrates synthesis of optimal difference-equation compensators for finite-time settling of both reference and disturbance step responses, along with a general approach for solving arbitrary difference equations on the analog computer.
