Demonstration device for proving logic algebra common formula

Abstract

The invention discloses a demonstration device for proving a logic algebra common formula. The demonstration device is used for proving that the logic algebra common formula is workable, namely, in an AND / OR expression, a product term A is included, if NOR of the A and OR of other variable B form another product term, in the another product term, the NOR of the product terminal A is redundant; the demonstration device comprises a first demonstration circuit and a second demonstration circuit in parallel connection, and a power supply serially connected with the first demonstration circuit and the second demonstration circuit which are in parallel connection; the first demonstration circuit shows the logical combination of the AND / OR expression in the logic algebra common formula to be proved; and the second demonstration circuit shows the logical combination of the AND / OR expression in the logic algebra common formula to be proved. Based on the design of visualized graphic thinking mode, the demonstration device provided by the invention can effectively enhance the understanding of the beginners facing the common logical problems in digital circuits, thereby effectively promoting the teaching effect.

Description

technical field [0001] The invention relates to a teaching instrument for proving common formulas of logic algebra, in particular to a teaching instrument for proving common formulas of logic algebra in the field of digital circuits circuit demonstration device.
