Name heaviside is not defined
WitrynaThe Heaviside condition, named for Oliver Heaviside (1850–1925), is the condition an electrical transmission line must meet in order for there to be no distortion of a transmitted signal. Also known as the distortionless condition , it can be used to improve the performance of a transmission line by adding loading to the cable.

An amplitude curve: allows arbitrary time (or frequency) variations of load, displacement, and other prescribed variables to be given throughout a step (using step time) or throughout the analysis (using total time); can be defined as a mathematical function (such as a sinusoidal variation), as a series of values at points in ...
WitrynaUser-defined functions support arbitrary input and output variables. User-defined functions can be defined within your main script file, or saved in separate files, and must be defined at global scope. If you save the function in a separate file, ensure the script file name is different than the function name. WitrynaBy IEEE convention, this function is defined for x2 = +/-0 and for either or both of x1 and x2 = +/-inf (see Notes for specific values). This function is not defined for complex-valued arguments; for the so-called argument of complex values, use angle. Parameters: x1 array_like, real-valued. y-coordinates. x2 array_like, real-valued. x-coordinates.
