![]() ![]() In the simulation settings window, expand the Time Domain tab. The Laplace Block LB1 behaves like a low-pass filter, flat at 0 dB (neither amplifying nor attenuating) until a corner with a -3 dB frequency exactly at 10 kHz, as expected.Ĭlick Hide in the plot window. Choose V1 as the Input source, increase Points/Decade to 50, and click the "out" node name to add DB(MAG(V(out))) and PHDEG(V(out)) to the Outputs list:Ĭlick Run Frequency-Domain Simulation. Double-click the node names to label them "in" and "out", wiring the circuit as shown:Ĭlick Simulate at the bottom of the window, then click Frequency Domain. This is the transfer function of a one-pole low-pass filter with a bandwidth of 10 kHz.Ĭlick the X to clear the toolbox search, and then click and drag to insert a voltage step source, a ground node, and two node names. Drag a Laplace Block to the schematic, and double-click it to edit its parameters:Įnter "1/(1 + s/(2*PI*10000))" in the TF (transfer function) box: Press / (forward slash) to begin a toolbox search, and type "laplace". ![]() Flip through the screenshots below to see how to use this to easily define filters and feedback loops. CircuitLab lets you work with Laplace Blocks directly. The Laplace transform lets you express differential equations as rational polynomials in "s".
