Requirements: 80286 or better DOS 6.0 or better 74K RAM 85K hard drive space available VGA monitor or better ABOUT OPSMTRIG: OPSMTRIG is a computer assisted circuit design program for the design of opamp based schmitt trigger circits. There are many circuits in electronics that are a standard configuration. The only difference is the component values, which are variable depending on what is required of the circuit. Knowledge of the many electronic math formulas are required to get the component values right for the desired output of these standard circuit configurations. It can take hours, days, even weeks of plugging numbers into these formulas to get the right component values. Then the component values have to be rounded to the standard values available on the market.Sometimes a prototype of the circuit must be built (especially if all the formulas are not known) and then troubleshot to get the right component values. OPSMTRIG eliminates all these problems. OPSMTRIG does all the head work, knows all the formulas, and selects component values that are available on the market. The electronics hobbyist's dream come true!
