👉 Ladder math, also known as ladder logic, is a graphical method used primarily in digital electronics and computer programming for designing and implementing sequential logic circuits. It employs a ladder diagram, where horizontal lines represent input signals, and vertical rungs represent logic gates or other circuit elements connected by wires. Each rung corresponds to a specific logical operation, such as AND, OR, NOT, or XOR, and the flow of signals through these rungs determines the circuit's behavior. The term "ladder" comes from the way it resembles a ladder with steps, where each step represents a single logical operation. This method simplifies the design process by allowing engineers to visualize and construct complex digital systems using intuitive, human-readable symbols. It's particularly useful for programming FPGAs (Field-Programmable Gate Arrays) and other reconfigurable hardware, enabling precise control over the timing and sequence of operations.
