Longest Path A B Do D E This longest path contains 3... Glitch Analysis and Reduction in Combinational Circuits. Hazard in digital circuits is unnecessary transitions due to gate propagation delay in that circuit. [...] In this paper, we analyse various Glitch reduction techniques such as Hazard filtering Technique, Balanced Path Technique, Multiple Threshold Technique and Gate Freezing Technique. - This means that there is propagation delay from the beginning of the line to the end of the line - In reality, all “wires” are Distributed. However, sometimes they are so short the propagation delay can be ignored. - We do this to simplify the circuit analysis: “Lumped System” the dependant variables (V & I) are only a function of time. Throughout this activity we used switches for the circuit inputs and a probe for the circuit outputs. Though this works fine for testing purposes, it is not practical for real-world applications of combinational logic circuits. List three input and three output devices that would be used with real world applications of combinational logic.
