Abstract
Schmitt trigger multivibrator circuit, capable of astable, monostable or bistable operation, incorporates an input circuit in conjunction with a Schmitt trigger circuit. The circuits form two output signal levels, are useful in switching circuit applications, initiates oscillations, and forms highly unsymmetrical wave forms.
