R-S Flip Flops

RS-type NAND Flip FlopA basic logical device for information storage is the flip-flop (abbr. FF). A flip-flop can stay in one of two logic states. ... wo logic states. To change this stage it needs a new input signal. Thus a flip-flop is a one bit memory. A flip-flop containing a 1 is said to be set, if it contains a 0 it is reset. There exist three ... is said to be set, if it contains a 0 it is reset. There exist three basic types of flip-flops:* Memory flip-flops have special inputs to be set or reset.

Digital Security System

security system. It was a complicated project, because we first had to research the different ways for the project to be done. Internet was the main way of research for this, and for the most part it ... if we used a digital security code. So that's what we did, we put together a complicated system incorporating a dual quad-input NAND gate, a quad dual-input OR gate, and an inverter. When the correct ...
