Abstract

A theoretical analysis of the action of a fundamental multivibrator has been undertaken along the lines of Van der Pol's analysis. A more exact approximation to the transfer characteristic has been used and an exact solution of the equations has been found in the case where the shunt capacities of the tube can be neglected. The analytical solution then allows one to localize the type of distortion in the "square wave" output and to suggest better circuits for the production of rectangular waves. Experimentally several circuits are presented in which the ultimate limit to the "squareness" of the square waves is limited only by the shunt capacities of the tubes.
