Cathode-Coupled Multivibrator Operation

An approximate analysis of the cathode-coupled multivibrator is given. The result is an expression for the period of the output pulse in terms of the circuit elements, rather than voltages which have to be determined graphically. A series expansion of the final expression is used to show that the output period is nearly a linear function of one of the voltages in the circuit, and can be made more nearly linear by a proper choice of the circuit parameters.
