Digital Electronics Notes, lectures for engineering and diploma students

SCR In Parallel

When the load current exceeds the rating of a single SCR, SCR’s are connected in parallel to increase their common current capability.

RL Filter Circuit

Simple RC circuits are not used in switching circuits, especially, in integrated circuit. However, inductors are still used, as in the case of current sweep generation, tunnel diode monostable and astable circuits.

Sequential Logic Circuits

In digital circuits, such as comparators, two 8-bit numbers may be considered to generate and output only when they are the same.
