Rectangular(square) wave in LTspice.(Usage "limit" function)

Usage "limit" function: limit(x, min, max)

For example,
V = limit(sin(10 * 2 * pi * time), -1e-2, 1e-2)



with offset
V = limit(sin(10 * 2 * pi * time), -1e-2, 1e-2) + 1e-2



steep slope
V = limit(sin(10 * 2 * pi * time), -1e-2, 1e-2) * 10


Read B-Sources part in Undocumented LTspice for more details.


1. Put two GNDs.


2. Then put a voltage source



3. Then put a Resistor or something, set parameter of it and wire them.




4. Then set parameter of the voltage source(in this step, sin curve is setted.)
Don't forget typing "V =" or error message will be apeared.
Don't forget typing "time" for argument in sin function or the transient shape will be DC.
for example,
V = sin(2 * pi * 10 * time)
in case of 10 Hz.




5. Run



V = sin(2 * pi * 10 * time)


V = limit(sin(10 * 2 * pi * time), -1e-2, 1e-2)
