DCircuit Lab is a tool to simulate combinatorial and sequential digital circuits. Circuits can be simulated in two ways: 1) one single step: all the outputs values are evaluated at the same time 2) step by step: outputs and gates are evaluated one step a time If circuit contains clock inputs, its simulation is dynamic. This means that outputs change accordingly to the clocks. During this dynamic simulation, user can change inputs values to study the circuit behavior which is also provided via a timing chart. Circuits are built using basic components, gates and flip-flops: * inputs (three state: 1, 0, X - undefined) * outputs * wires * NOT, AND, NAND, OR, NOR, XOR gates with any number of inputs * Flip-flop RS, JK, T, D (Positive or Negative Edge Triggered and with Set and Reset Inputs) * Multiplexers with any number of inputs * Demultiplexers with any number of outputs * Fully configurable Clocks * Custom Components defined by their truth table * BCD to 7 Segments Display Decoder * 7 Segments Display Some video tutorials are available directly from the application to learn how to use it.

About

CapacitorCalc

Features
Read full description

Easily calculate the minimum required capacitor value for your AC‑DC transformer circuit. This app helps you determine: • The minimum capacitance needed (in pF, nF, µF, mF or F) • The minimum ripple voltage across the capacitor Just enter the voltage, current, and frequency of your transformer — and get instant results. Great for electronics enthusiasts, students, and hobbyists working with power supplies or rectifier circuits.
