WebApr 19, 2024 · So excuse my confusion. My issue is with my ALU. The ALU Opcode is a 4-bit number, and the SubOp is a single-bit value. When I try to test my ALU, all of my lines to the output are red. I'm not sure why exactly. If I delete the NOR Gate's output, all other lines go black. And then when I change my Opcode (lower left of the image) from the AND ... http://www.cburch.com/logisim/docs/2.3.0/libs/mem/flipflops.html

WebCLEAR input is used to directly put a “0” in the Q output on the JK Flip-Flop. The PRESET and CLEAR inputs of the JK Flip-Flop are asynchronous, which means that they will have an immediate effect on the Q and Q’ outputs regardless of the state of the clock and / … WebSep 27, 2024 · PRESET and CLEAR: D flip flop has another two inputs namely PRESET and CLEAR. A HIGH signal to CLEAR pin will make the Q output to reset that is 0. Similarly a HIGH signal to PRESET pin will make the Q output to set that is 1. Hence the name itself explain the description of the pins. IC Package: how to make stone axe in minecraft
