Bode Plot Calculator vs Circuit Simulator bitGateLab

This is not a standard scientific calculator, it is optimized to evaluate Bode plots and Nyquist diagrams. This calculator is also fully compatible with the complex domain and standard graphs in time domain (linear). Writing a calculation produces the numeric result, as any calculator, while adding the variable t produces a plot in time domain. Inserting f, omega or s instead, produces the Bode Plot, then it is possible to switch to the Nyquist diagram. Functionalities: - Nice looking interface, intuitive, immediate and able to not only replace, but to enrich hardware calculators. - Elegant and modern themes and colors to choose from, all included in the first purchase. - A little magic feature: in scientific notation, swipe over the result to move the decimal dot and see the ten power change :) - All scientific function (sin, cos, tan, ..., log, ln, exp, ..., atan2). - Calculation structured in 2D, with fractions, powers, roots, brackets and so on, with very easy to nest operations, no limits! - Tap on the calculation to place the cursor and write. - Undo/Redo buttons - A catalog with 40 physics fundamentals constants, with name and unit of measure, ready to be inserted. - Possibility to store values. - Chronology. - Sliders: yes, you can insert many parameters and change them swiping on a slider to see the effect in real time. - Spaces: access to up to 4 spaces on which you can edit and keep calculations, useful also to superpose different plots. - Joystick mode: swipe over the buttons to move the cursor (still in beta). - Bode Plots: inserting a variable, s, omega or f, produces the Bode Plot, toggling on the button it switches to the Nyquist diagram. - Linear Plots: inserting the t variable, produces a plot in a linear domain. - Complex numbers: the app automatically uses complex numbers when needed, no need to set the complex mode. - Plots also support for complex values. - Integrals and derivatives (in the future also limits). - Export plot and calculation as image/PDF, copy result as text

Circuit Simulator bitGateLab is an electric circuits and analog electronics lab on your PC, phone or tablet: draw a circuit, measure it with multimeters and an oscilloscope, get its frequency response, turn it into block diagrams with the Laplace transform and build it on a 3D breadboard. Works offline, no account required. DRAW AND SIMULATE • DC, AC with phasors and time-domain transients, using modified nodal analysis (MNA), the same method SPICE uses. • Resistors, potentiometers, capacitors, inductors, transformers, thermistors and LDRs. • DC and AC voltage and current sources, a signal generator (sine, square, triangle and ramp) and dependent sources. • Diodes, Zener, LED, Schottky, NPN and PNP BJTs, N- and P-channel MOSFETs, JFETs and op amps with supply rails. • Undo and redo, copy and paste, rotate, replace components and node labels. MEASURE LIKE IN THE LAB • Voltmeter, ammeter, wattmeter and a multimeter-style probe on any node, pin or component. • Multichannel oscilloscope with a trace of every signal over time. • Bode plot (magnitude and phase) plus DC and frequency sweeps. LAPLACE AND CONTROL • Block diagrams: gain, H(s), integrator, differentiator, PID, delay, summing junction and saturation. • Turn your circuit into blocks and get its transfer function H(s). • Step response, poles and zeros, Bode plot and step-by-step diagram reduction. 3D BREADBOARD • Your circuit builds itself on a breadboard with resistors, capacitors, transistors, sources and wires. • Rotate, zoom and choose isometric, top, front or side view. PRACTICE EXERCISES • Generate fresh exercises on series-parallel simplification, mesh and nodal analysis, the Wheatstone bridge and AC RC, RL and RLC circuits. • Each exercise comes with its circuit, a graded question and a step-by-step solution. IMPORT AND EXPORT • Open SPICE netlists (.cir, .sp, .net) from ngspice or LTspice, including model libraries, and Falstad circuits. • Export to SPICE, Falstad and CircuiTikZ for your LaTeX documents, or as an image or PDF. FREE AND PREMIUM • Phone and tablet: every feature free, with circuits of any size and with ads; Premium removes the ads. • Premium: a monthly or yearly subscription, or a one-time lifetime purchase. FOR LEARNING AND TEACHING • Designed as a companion to an electric circuits course: whatever you work out by hand, you can check in the simulator. • Light and dark theme, European or American symbols. • 45 languages.
