A wide-band square-wave generator

A square-wave generator is described which covers a very wide frequency range, is compact, self-contained, and adaptable to many other uses besides the investigation of transient response. The instrument uses a positive-bias type multivibrator. The operation of the multivibrator and clipping circuits are explained. Approximate formulas for the multivibrator frequency and pulse width are derived and discussed and its increased stability against interference explained. Methods and fields for application are then discussed.
