Diode logic (DL), or diode-resistor logic (DRL), is the construction of Boolean logic gates from diodes. Diode logic was used extensively in the construction of early computers, where semiconductor diodes could replace bulky and costly active vacuum tube elements. The most common use for diode logic is in diode–transistor logic (DTL) integrated circuits that, in addition to diodes, include inverter logic to provide a NOT function and signal restoration. While diode logic has the advantage of simplicity, the lack of an amplifying stage in each gate limits its application. Not all logical functions can be implemented in diode logic alone; only the non-inverting logical AND and logical OR functions can be realized by diode gates. If several diode logic gates are cascaded, the voltage levels at each stage are significantly changed, so diode logic is normally limited to a single stage, though, in special designs, two-stage systems are sometimes achieved.

In this veideo we continue our look in to the dihedral groups, specifically, the dihedral group with six elements. We note that two of the permutation in the group are special in that they commute with all the other elements in the group. In the next video I'll show you that these two el

Dihedral Group (Abstract Algebra)
The Dihedral Group is a classic finite group from abstract algebra. It is a non abelian groups (non commutative), and it is the group of symmetries of a regular polygon. This group is easy to work with computationally, and provides a great example of one connection between groups and geo

Vacuum Tubes: Episode 7 – Let’s Build an SR Flip Flop / Latch!
In this episode we put all of our knowledge about different tubes into one place and build some NOR gates, which we hook up into an SR Flip Flop. There’s lots of ways to go about building an SR Flip Flop and we take at three different ways on the breadboard. Thanks for watching! IBM Pi
