Digital pattern generator

Digital pattern generator: During the construction and testing of digital circuits, there is often a need for an accurately defined bit pattern. The generator described here uses an EPROM to store the bit information for the desired pattern. When switch S1 is pressed, a given pattern is generated once; seven different patterns can be generated simultaneously. The eighth[…]

Digital (tape) Counter

Since there are still tape records about that have no mechanical tape counter, the circuit shown here offers an excellent, electronic add-on for these. It can, of course, also be used to replace a mechanical counter. Furthermore, it can be used for other applications, for instance, as the hoist-height indicator for a model building crane,[…]
